By: Sandy Dean: Many people realize that it’s very important to know precisely when you ovulate when you are trying to chose your baby’s gender at home. But sometimes, it isn’t so clear what should you do once you get that positive that tells you that ovulation is imminent.
I heard from someone who said: “I’ve been testing for ovulation since the last couple of days of my period. I wasn’t sure when I ovulated and I didn’t want to risk missing it. Finally, I got a positive reading this morning. I want a boy baby, so when should I start having sex? What does this positive reading really tell you? My husband is at work. Should I call him home? Or should I wait a little while to have sex?”
It’s very important that you read the instructions that come with your kit. Most will spell out exactly what a positive reading means. However, with this said, most of the time, a positive reading means that an LH surge has been detected. The test is telling you that there is the presence of luteinizing hormone and this generally happens right before you ovulate. Granted, there are certain medical conditions (like polycystic ovary syndrome or PCOS) that cause people to produce this hormone without ovulation being imminent. But if you have one of these conditions, you probably already know it and are under a doctor’s care. Most people agree that a positive reading means that you will be ovulating within 12 – 24 hours. And if you are testing every day and you tested negative yesterday, then it’s a pretty good guess that the luteinizing hormone was released very recently and that by tomorrow or very soon thereafter, ovulation would have already passed.
That means that by tomorrow or so, your egg should be ready to be fertilized. Now, boy producing or Y sperm are faster than girl producing or X sperm, but they also die off more quickly. That is why it is beneficial to wait have sex until after ovulation when you want a son. Since you know that this time period is either happening right now or will happen very soon, it makes sense to go ahead and have intercourse as soon as is feasible. Your egg can live for a day or two before it starts to deteriorate. So it is best to not wait too long. Since the boy sperm dies off relatively quickly as well, it makes sense to try to optimize the health of both the egg and the sperm. That’s why I think it makes sense to go ahead and begin having sex shortly after you get a positive reading.
With that said, I don’t think that you need to call your husband to rush home right that very minute. But having sex that evening is probably optimal. Many people ask if they should continue having sex after the initial positive reading. This can be a good idea when you are trying for a boy because you are maximizing each attempt. Since more sperm chromosomes are released this way, this gives you more speedy and healthy boy sperm that is fighting for the egg. However, this isn’t thought to be optimal if you want a girl baby. Most couples that are trying for a girl will have stopped having sex once they get the positive reading. Because a girl conception is more likely if you conceive early since the girl sperm have greater longevity. So for people that want a girl, that positive reading signals the time to stop intercourse and wait to see if you are pregnant. If not, you simply try again the next month. For couples wanting a boy thought, that positive reading is usually a green light to begin having sex relatively quickly.
I hope this article has helped you with your timing. But know that your PH and the sexual positions you use are also important in choosing your baby’s gender. If you’re confused about either one of these variables, I’ve put together a few websites that take a lot of the guess work out of this.

Can A Man Make His Sperm Conceive A Boy Or Girl Baby? Can He Influence Whether He’s Producing Girl Or Boy Sperm?
By: Sandy Dean: I sometimes hear from women who are either with a man who has had many children of one gender or the woman is in that same situation herself. For example, the woman may have conceived all daughters or she has recently married a man with all sons. Often, the couple are trying to reverse that trend and get a baby of a new gender. And they are often wondering if the man has any control over which sperm chromosomes he will produce during this process.
I heard from a woman who said: “I had three boys with my previous husband. I am getting married to a man who also has two boys. Needless to say, I want a girl baby with my new husband. I have been very clear about this and my husband is telling me that he can control his sperm. I told him that this is crazy talk but he says that he can control what happens with his thinking and with his diet. Can men control whether they are producing boy and girl sperm? He is telling me that he will make sure that I get a girl baby this time and I know that he wants to please me. But is this a promise that he can even make? Is this even possible?”
I wish that I could tell you that this was true. But I don’t believe that it is. I will tell you why in the following article.
There Is Overwhelming Evidence That Men Have Equal Amounts Of Both Girl And Boy Producing Sperm Regardless Of The Gender They Have Previously Produced:
There have been studies where men who have produced several of one gender have been tested to determine their sperm production ratio. Some expected to find that men who had only produced boys had more Y (boy producing) than X (girl producing) sperm. And, it would also be expected that fathers of nothing but daughters would have much higher amounts of X sperm.
But, this was not the case. Instead, all of the men showed equal amounts of each type of sperm chromosome regardless of whether they had boys or girls. I know that this is suprising to many, but this has been shown more than once. So if we accept that the man in question very likely had equal amounts of X and Y sperm, he already had an equal chance of getting a girl baby, unless the woman or mother to be was influencing the outcome which I will discuss a little later.
Although There Are Things That Men Can Do To Increase Their Sperm Count, They Can’t Isolate The Sperm That They Are Increasing:
If you’ve spent any amount of time researching becoming pregnant, you’ve probably already read about how men can increase their sperm count to have a better chance of conceiving quickly. But, although they can increase their sperm, they are also increasing both X and Y chromosome relatively equally. And they aren’t increasing only the X’s and not the Y’s or vice versa.
Consider Looking At How The Mother To Be Might Be Contributing To Baby Gender:
Since the father to be’s sperm ratio appears to be set, it makes sense to look at how the woman or the mother to be is contributing. It’s a common assumption that she doesn’t contribute at all, but I highly disagree with this.
Her timing, vaginal PH, and the sexual positions that she uses can all make one gender more likely than another. For example, some things can discourage the Y sperm which means that a girl baby is more likely. Having a successful conception before ovulation, having an acidic vaginal PH, and using deep penetration without female orgasm would all help to weed out the Y sperm to increase the odds of getting a boy baby.
So if you are a female who is conceiving one gender over and over again, I would take a close look at your vaginal PH as well as your ovulation time as it relates to when you are having conception intercourse.
But to answer the question posed, while it’s reassuring to think that a man can think powerful thoughts or change his diet to get the gender of his choice, it’s not likely to happen because his ratio is going to be roughly 50 / 50 no matter what. While there are things that he can do to increase his sperm count, these things will increase both X and Y sperm in equal ratios and this doesn’t change no matter what he does or thinks. I wish it were different but science has shown that it isn’t.
The good news is that the woman often is able to control some variables as far as she is concerned. So it makes sense to turn your attention there.
If this is still a bit confusing to you or you’re wondering where to start to influence your baby’s gender, I’ve put together a couple of web sites that breaks this down into small steps. If you want a boy baby, check out http://conceive-a-boy-baby.com/

By: Sandy Dean: It’s not uncommon for women who already have a baby of one gender to assume that they are likely to get the same gender when they become pregnant again. What I mean by that is that mothers of daughters might suspect that they will have difficulty conceiving a son the second time around and vice verse. Some worry that the method that they used the first time around might come into play this time.
For example, a woman who had a girl might say: “for my first pregnancy, I conceived in June and had a daughter. This was ideal because the part of my pregnancy when I became big occurred when it was not so hot outside and I was comfortable. I honestly wouldn’t mind conceiving in the summer again, but this time I want a boy. One of my friends say that if I conceive in the same month as I did with my daughter, then I will have another girl. Is this true?”
Well, it could be true, but not because of the month in which you conceived. Unless you are using special methods to get the gender of your choice, you have about a 50 / 50 chance of getting either gender. A man’s sperm has equal numbers of girl and boy producing sperm and this doesn’t change, no matter what month you are trying to conceive in. Things that can influence baby gender are: the woman’s vaginal PH; the sexual positions used; whether orgasm took place (because it changes vaginal PH,) and when the woman ovulated in relation to when she attempted to conceive. None of these things have anything to do with the month or the season. And you can change these variables at any time during the year.
So for example, when you conceived in June, you may have had an acidic PH (which is hostile to boy sperm) and you may have ovulated before ovulation and used shallow penetration when you attempted to conceive. All of these things would have discouraged boy sperm and encouraged girl sperm. As you might deduct, if you had used the same methods in November, you may have gotten the same result.
So yes, if you do nothing the odds may give you the same gender that you had before as you have 50 / 50 odds anyway. But if you want the opposite gender, then you’d just change up the variables needed for a boy (an alkaline PH, conceiving after ovulation, and the right sexual positions.) This can be done January through December, to be honest. So there would be no reason that you could not conceive a boy in June. You’d just want to keep an eye on the variables mentioned above.
To help you better understand how the variables come into play and when to implement each one, I’ve put together a couple of free websites that outline the process to choose your baby’s gender step by step.

By: Sandy Dean: I often have people who ask me about the optimal time to have sexual intercourse in order to get pregnant with a certain gender. Many people realize that the day on which they conceive can be a very important factor in terms of whether they get a girl or boy baby. To that end, people sometimes ask or wonder if they should be having intercourse on even or odd days.
Someone might ask: “my husband and I would like to have a boy baby. My mother in law said that you should have sex on odd days for a boy baby and on even days for a girl. I told her that this is probably an old wives tale but she swears that this is true. How can this possibly be accurate?”
I honestly don’t believe it is accurate. I think that people probably gave this advice back in the old days because they thought that this advice would ensure that a couple was only having sex every other day and therefore ensuring a high sperm count during conception.
Understanding How Pregnancy Happens: One way to show you how this theory is a bit outlandish is to understand how a woman gets pregnant. A woman is fertile during a time period just before, after and during her ovulation period. This spans different time frames for different women, but it is only a few or a handful of days out of each month. If you are having sex on alternating days, then you are cutting into an already small window with no consideration given to when you can actually become pregnant.
Variables For Gender Selection: Now, let’s look at what might help you get a girl or boy baby. A man’s sperm has two different chromosomes that affect baby gender – Y (boy producing) and X (girl producing). These chromosomes have different characteristics. The X or girl producing live for longer and the Y or boy producing are faster.
That is why when you want a girl baby, you’re advised to have intercourse before ovulation. And you’re encouraged to wait until after this time frame when you want a boy. Notice that it doesn’t matter if either of these days are even or odd. As an example. Let’s say your menstrual period happened on the fifteen of the month. Now, let’s say you ovulate on the first day of the next month and you want a boy. Because having intercourse after ovulation is important for a boy baby, your optimal day to have sex is going to be the 2nd and after. The 3rd was also work. Notice that one day is even and one day is odd, but they are both optimal for a boy baby because they happen after ovulation.
To answer the original question though, the best day isn’t either or odd. It is the day before or after your ovulation day depending on which gender you want. To take it even further than that, the best day is not only when your timing is right, but when your PH is right also. PH and sexual positions matter too. And none of these things have anything to do with odd and even days on the calendar.
If you’d like step by step instructions of how to combine all of these variables and when, I’ve put together a few websites that explain it more directly. If you want a girl baby, see http://conceive-a-girl-baby.com If you want a boy, check out http://conceive-a-boy-baby.com
By: Sandy Dean: I sometimes hear from women who want to know that their boyfriend or husband needs to do to help them conceive a boy or girl baby. Occasionally, I hear from the men themselves who are trying to do everything in their power to help the woman they love get the baby gender of her choice. The truth is, there is plenty that a man can do to help conceive a boy or girl baby. But sometimes, his role is more of a supporting one, which might come as a surprise to you.
Here are a few examples. Many people ask me what the man should be eating to achieve a certain sperm PH. Or they want to know if he should restrict himself in terms of food, exercise, or the clothing that he wears. The truth is, the PH of his sperm does not affect baby gender in the way that a woman’s PH does. Plus, men have a 50 / 50 ratio of Y to X sperm (boy and girl producing.) And this is typically true no matter what his family history is (in terms of baby gender) and no matter what makes up his diet.
There have been studies which show that even men who have had only boys or only girls still have these same ratios. I know that men can be desperate to help and are more than willing to tweak their diet or their lifestyle to help their partner get the gender that she wants. But this just isn’t necessary as it is vaginal PH (rather than sperm PH) that really matters. With that said, there is definitely a part that a man can play, which I’ll discuss below.
Be Willing To Wait Until The Time Is Exactly Right To Have Sex: I know that it is very exciting when you are trying to conceive. When your wife or girlfriend gives you the green light that it’s time to make a baby, then it’s normal to want to get right to work and to let the fun begin. However, there is often a very good reason to wait. When you are trying to chose your baby’s gender, you often have a much smaller conception window than you would if you didn’t care about baby gender. Because if gender doesn’t matter, you can have sex anytime in the larger fertility window. But for a girl baby, you want to have sex only before ovulation. And for a boy, you want to only have sex after it. So there will only be a few ideal days for conception. Some days will have to be passed up. Understand this and plan accordingly.
Know That You’ll Need To Invest In Some Tools And Do Some Detective Work: The biggest mistake that I see people make when they are trying to chose their baby’s gender at home is that they will assume that they know when they are ovulating without actually testing themselves. Or, they hope that they have the right PH without really knowing for sure. Guessing is the worst thing that you can do. Make sure your girlfriend or wife has a good ovulation predictor and PH tester and, more than that, make sure she uses it regularly and uses the applicable charts for both.
Understand That The Act Of Sex Many Not Be As Spontaneous As Usual: I know that it’s very romantic and exciting to think that when you have sex, you might be creating a baby. But it’s important that you decide on the sexual position that you will use ahead of time. When you are not trying to conceive, being spontaneous with the timing of sex and the positions that you use is fine. But when you are trying to conceive, your sexual positions can matter a great deal. For a girl, you want to use shallow penetration. And for a boy, you need deep penetration. What positions that accomplish these things vary from couple to couple.
I know this might sound staged and planned (which isn’t as much fun,) but there’s a reason for this. Deep penetration helps the weaker boy producing sperm with the shorter shelf life. And shallow penetration is better for producing girl babies because it discourages those short lived Y’s (which contain boy producing sperm.)
I know that I’ve given you a lot to keep track of. If it helps, I’ve put together a few websites that contain cheat sheets to take a lot of the guess work out of choosing your baby’s gender. If you want a boy baby, check out http://conceive-a-boy-baby.com/

By: Sandy Dean: I sometimes hear from young couples who want to try to become pregnant. Understandably, they are excited about the prospect of starting a family and they want to get started right away. They also want quick results – so many of them will figure that quantity is important in this process. By that I mean that they have chosen to have sex frequently – say, every other day. They figure that by doing so, they can cover all of their bases and not leave any day that could be a conception day “wasted.”
For example, someone might say: “once my husband and I made the decision to have a baby this year, I decided why waste any time? We stopped using condoms immediately. And now we have decided to have sex every other day. I don’t want to lower his sperm count by having sex every single day. And I know that sperm can last for a while, so I figure that alternating days have me covered. But I’m wondering what this schedule will do in terms of giving me a girl or boy baby? Which is more likely?”
That’s hard to predict because when you are using the on / off schedule, there is no way to predict if you are actually going to ovulate on an “off “day or an “on” day. And this is vitally important. Your ovulation day (and when you have intercourse in relationship to it) can largely impact your baby’s gender. I understand your thought process, but I think that your plan could be better. Why? Because what if you ovulate on the morning of an “off” day? If you want a boy baby, then it’s best to have sex pretty quickly after you have ovulated. But if that’s your “off” day, then this timing isn’t optimal. Of course, if you ovulate and then have sex on your “on” day, then this would favor a boy baby.
Now, if you wanted a girl, then this alternating schedule still has some flaws. If you are trying for a girl, you want to have sex well before ovulation, BUT you want to stop having sex once ovulation happens. You can’t do this if you are still following that alternating schedule.
The better way to go about this is to be very well aware of when you ovulate. You can easily do this by using saliva or urine ovulation predictors. (You can see examples of the saliva sticks on Ebay here.) If you want a girl, you may want to give yourself a month to get a good feel of when you ovulate so that you are ready to go the next month. Once you know EXACTLY when you ovulate, then you can have sex accordingly, depending on the gender that you want. (Although please do be aware that some women ovulate at different times on different months.)
While the alternating schedule does assure frequency, it is like trying to hit a bull’s eye that you can’t see. But if you are using an ovulation predictor and know when you are ovulating, then you can see your target much more easily. The more information that you have, the easier it is to be successful in choosing your baby’s gender.

By: Sandy Dean: Most people who want to conceive in the near future realize that a woman typically only has a certain period of time in any given month when she can become pregnant. A woman will typically have a menstrual period which is eventually followed by an ovulation window. This ovulation period is when a woman is most likely to conceive. It is the time of the month when her egg is ready to be fertilized and is then released so that sperm can fertilize it for a pregnancy.
Naturally, people wanting to conceive will try very hard to identify this ovulation window and then to have sex around it. This ensures that you have the highest chance of actually becoming pregnant. But some wonder what happens once you DO have sex during this time period. Does the act of having sex stop your window? Do you only have one shot at this?
Someone might say: “my wife has one of those ovulation predictor things that you pee on. My understanding is that once she gets a positive, we should have sex because that means that she is ovulating. But does having sex mean that her ovulation stops? Are there chemicals released or something that stop the ovulation? We want a girl baby, so we want to make sure that we get it right.”
Actually having sex does not influence the ovulation at all. Frankly, you could not stop this process (once it has started) if you tried. A woman’s egg release has more to do with hormonal changes that relate to her monthly cycle. In the days leading up to ovulation, she is still fertile because a man’s sperm can actually live for some time inside of her body. So even if the egg has not yet been released, sperm that is waiting on the egg can still fertilize it.
Once the egg is released, the window begins closing because both the sperm and the egg are only viable (and can survive) for a short period of time. This means that you can have sex for a few days before ovulation actually happens and also on the day of ovulation (or very shortly after it) and still get pregnant, regardless of how many times you have sex. The frequency of sex does not stop the ovulation.
Now, some people do feel that you should be deliberate with how many times you have sex during this period because if you have it too much, then sperm count (and also the quality) will be lower. The validity of this depends on the man’s sperm count (and the quality of it) to begin with. But to answer the question, no, having sex doesn’t stop ovulation. In fact, in order to get pregnant, you’ll need to have it at least once during that window. But nature wouldn’t be so cruel as to give you only one crack at it. Yes, the window is only open for a short period of time, but you can have sex more than once during the window without it stopping ovulation.
As far as gender selection goes, the timing of sexual intercourse matters here. If you conceive days before ovulation, you have a better chance of getting a girl, which is why waiting to get a positive using the pee or urine ovulation sticks are too late. In my opinion, the saliva sticks are better because they give you more warning, especially if you want a girl. (You can see examples of the saliva sticks on Ebay here.
If you’re interested in steps to take to make sure you get the gender of your choice, I’ve broken it down on a couple of websites. If you want a boy baby, see http://conceive-a-boy-baby.com. If you want a girl, see http://conceive-a-girl-baby.com
By: Sandy Dean: It’s understandable that women trying to become pregnant with a certain gender spend a lot of time trying to determine the optimal day on which to conceive. This is important because if you get your timing wrong, you could accomplish the exact opposite of your goal. A couple who wants a boy could get a girl and vice verse.
If you’ve been researching how to get the gender of your choice, then you know that your vaginal PH and your timing are two very important variables in this equation. So women in this situation naturally wonder when their vaginal environment is going to be optimal. Women who want a girl will want to know when their vaginal environment is naturally acidic (which is ideal when you want a daughter) in the same way that women who want a boy baby want to know the ideal time that their environment is most alkaline (which is what you want to conceive a son.)
A question you might get in this situation is something like: “I’ve heard that early in your cycle, you’re more acidic, but are also more alkaline later on. Is this true? What days of the month are more likely to be acidic and which are more likely to be alkaline? I want a boy, so I am looking for alkaline days.”
I’m not a doctor or specialist, but I can tell you what I have found from my research. It’s thought that many women tend to be slightly acidic naturally because this state discourages infections. If you have reoccurring yeast or bacterial infections, then you might trend toward being naturally alkaline. However, one’s natural PH varies from woman to woman and you can easily test this.
Plus, there are many things that can change your PH. One thing that potentially changes it every month is ovulation. When a woman ovulates, her cervical mucus changes and becomes more thin. This makes her vaginal environment slightly more alkaline and this is a more friendly environment to the sperm. (An acidic environment is more hostile and that is why an acidic environment is said to encourage the much more hardy girl sperm.)
Other things that can change your vaginal PH include hormonal changes; (like ovulation, but also things like thyroid issues, medications, etc.) using perfumed feminine hygiene products; douching; and strict or harsh diets. One common thing that can change the PH very dramatically are tampons and the chemicals that they contain. Also, they hold fluids in the vagina, which can cause additional PH fluctuations. That is why some women tend to get infections after their menstrual period. (However, since most women ovulate well after their menstrual period and have been free of tampons for several days, this usually doesn’t come into play.)
If you, like most women tend to be slightly acidic right before ovulation, it makes sense that ovulation would help you become slightly alkaline. This happens without your needing to do anything. If the woman has an orgasm during sex, this helps to create an environment that is more alkaline still. But whether you are at the optimal level isn’t going to be obvious unless you test yourself to be sure.
If you want a girl, you may have to test yourself and then experiment with douches or diet to get back to an ideal acidic state. Or, you may start out so acidic that this adjustment isn’t needed. If you want a boy, the act of ovulation might be enough to get you alkaline, but you can’t possibly know that unless you test yourself which leads me to my next point.
The best way to know your starting level and then to know where you are when you conceive is to test. The PH strips are easy to find and inexpensive. If you test yourself prior to trying to conceive and find that your level isn’t great for the gender you want, then you can always tweak it with your diet and with douching. Even then, you still need to test right before you attempt to conceive to make sure the level is still right.
This is only applicable if you care deeply about the baby’s gender, of course. If that’s the case, it makes sense to take the extra effort to make sure that everything is optimal.

If My Period Changes Dates From Month To Month Does This Mean I Can’t Become Pregnant With The Gender Of My Choice
By: Sandy Dean: Most women who are either trying to become pregnant or trying to avoid a pregnancy realize that the timing of their period becomes very important. Because the menstrual period is at least indicative that ovulation has already occurred for the month – so you can plan accordingly. After all, in the vast majority of the cases, a period occurs because no pregnancy has taken place for that month. And your ovulation and menstrual cycle start all over again. (I say “the vast majority” of the cases because some women actually have continued to have periods even while they were pregnant. It is relatively rare. But it does happen. So you can’t say with one hundred percent certainty that you are not pregnant once you get your period, but for most women, this is the case.)
Whether a woman is trying to avoid or achieve pregnancy, she will often use her period to gauge when she might need to avoid or attempt sex (and therefore a pregnancy.) But what happens when your period is hard to gauge? What if you are trying to become pregnant and your period happens at various times throughout the month? For example, someone might ask: “are you even fertile if you have periods at different times from month to month and when the date is always changing? I want to become pregnant, but last month, my period came on the 20th and this month it wasn’t until the 28th. So I have no idea when I can become pregnant. This would be hard enough if I didn’t care about gender. But I do. I want a girl and I have heard people say that this is going to be even harder to achieve? Can you become pregnant when you are always having your period on different dates? Can you get the gender that you want?”
The Timing Can Work If You Are Careful: The answer is yes on both counts, and I will explain why. You don’t need periods to happen in the same way every single time to become pregnant. Many women have cycles that vary from month to month. And your menstrual cycle (your period) and your fertility cycle (where you ovulate) are two different things. Ovulation occurs first when the egg is ready to be fertilized. If there is no sperm present to fertilize the egg and no pregnancy occurs, then your period starts. These two parts of your cycle can both vary as to when they occur. Certain factors can delay or affect them. And some women just have cycles that vary naturally.
However, this doesn’t mean that both processes aren’t happening normally even if their timing might be a little different. Now, determining when they might occur can be very important when you are trying to become pregnant. Because you want to have sex AROUND the time of ovulation. The egg only lives for a short while. So if you have sex too early before the egg is released then you won’t be able to become pregnant. If you wait too late after the egg has been released, then the egg won’t be viable anymore. That’s why timing is so important.
Knowing EXACTLY When The Timeframe Is Optimal: The good news is that you don’t have to guess. Ovulation predictor kits mean that you can know when this has occurred so that you can have sex at the appropriate time (and when pregnancy and conception are most likely to occur.) In terms of baby gender, this is a bit more tricky. Because the timing needs more precision in this case. For a boy, you want to have sex after ovulation. This isn’t that difficult because no matter when your period occurs, the ovulation kit can tell you exactly when you are about to ovulate. You know ovulation is very close so if you have sex a short time later, then you are a little more likely to get a boy. A girl conception is a bit harder because by the time you get a positive reading in most kits, you’re at the timing for a boy. That’s why the saliva predictor (as opposed to the urine) kits are better for couples who want a girl. They are more sensitive and give you a more generous lead time, which is more conducive to a girl baby.
But no, having your period at different times of the month doesn’t mean that you can’t become pregnant. You likely can, at least in my opinion. You may just have to monitor with a kit, but this is very easy to do. And if you want a certain gender, you’ll have to monitor a little more closely and use other methods.
Now, timing isn’t the only variable that matters. If you’re trying to control your baby’s gender, timing is very important, but you also need to consider PH and the sexual positions used. I have set up free websites to explain each of these variables in ways that I hope are easy to understand. I’ve put together a couple of cheat sheets to try to make it easy.
