You: Having a Baby: The Owner’s Manual to a Happy and Healthy Pregnancy. Michael Roizen F.

after all, only half his genes are yours. Your relationship with him isn’t exactly hostile, but it’s not always warm and fuzzy either. Even at this young age, he’s going to try to assert himself, and your body may try to resist. There are evolutionary reasons for this, which we’ll discuss in the pages to come, but you can also think of these initial rebellious acts as practice for the years ahead.

      Pregnancy can be as elegant as a waltz, as high-energy as a salsa, and as scattered as a twist (with a whole lot of shouting). Our main goal in YOU: Having a Baby is to teach you about this ingenious biological dance—a dance in which you have the ability and the artistry to guide your baby not only to a healthy delivery, but to a lifetime of good health as well.

      What’s in It for YOU

While many pregnancy books tell you what to do, we aim to add a deeper level of meaning in true YOU style and explain why. After all, when you truly understand the why, the what is much easier to adopt. Instead of giving you a week-by-week or hiccup-by-hiccup guide to pregnancy, we’re going to take a more holistic approach, focusing on how your mental and physical health affect your baby, and how—at the same time—pregnancy affects your mind and body. Of course, we’ll provide plenty of our signature YOU Tips and YOU Tools to help you make the best choices for a safe and healthy pregnancy, but we’re going to take you there a little bit differently than other pregnancy guides may. Here’s what you can expect^* from us:

We want you to understand at the base level how epigenetics works and why it’s important. Starting with the moment you go from making love to making a baby,^† we’re going to explain how you can influence your child’s development through this field—perhaps the most important developed in the last decade. Many of us believe that the genetics of our children are predetermined the moment that the sperm radar locks on its desired egg. But the truth is that research from various sources is suggesting that during pregnancy, you may actually be able to turn your future baby’s genes on and off. Epigenetics is not just how the musical notes of our genes are played but also how loud the volume is turned up. Since the acoustics in the womb and the real world might be different, we want these as aligned as possible. And that’s where all the magic takes place, no matter where you are in pregnancy or in parenthood. You have the ability to control genes anytime.

      You’re also going to learn quite a bit about the key player that mediates between you and your baby, transmitting all the signals that create those epigenetic changes. That player, which gets about as much attention as a dollar bill on a blackjack table, is the placenta. This beautifully functioning organ is the place where mom and child interact, where nutrients are exchanged, and where growth and development patterns are determined.

      After explaining the workings of the placenta, we’ll focus more closely on nutrition (both yours and baby’s), explaining how too much, too little, or the wrong nutrients all play roles in the health of both you and your child. Here you’ll discover why the thought of food makes you green on some days, while other days you long for an artichoke-heart milk shake. We’ll also talk about such things as fetal brain development, how to manage (and prevent) postpartum depression, and important pregnancy-related medical conditions like gestational diabetes.

      In the second half of the book, we’ll help you manage the wide range of side effects you may be feeling—everything from heartburn and insomnia to medical complications like preeclampsia. Finally, we’re going to present a bunch of great features you can use, including:

      Broadway to Birth: Our cool, interactive board game will take you through the amazing adventure that is labor and delivery to help you understand which elements you can control and which elements you need to leave to the pros (whom we’ll help you choose, based on your own labor and delivery goals).

      A Top Eight List of Postpartum Issues: And after you deliver your baby, you’ll appreciate our chapter on everything you need to know to take care of yourself and your newborn in the first month of life. This is where the second adventure begins.

       The Ultimate Pregnancy Flight Plan: Step by step, we provide the instructional dials, controls, and levers that will allow you to pilot your way to a safe landing. After all, you’re carrying a very precious passenger. This plan is the shorthand version of all the best tips and strategies we give throughout the book.

      YOU Tools: At the end of the book, we will give you specific advice about exercise, diet, vitamins, and the like that should serve as an action plan not only for pregnant women, but really for all potentially fertile women (that’s because 50 percent of pregnancies are unplanned, and the actions you can take for your baby can start at least three months before sperm and egg mate). We also provide guidance on everything from choosing a doctor or midwife to preparing your home for a baby to recipes your partner can make for you during your pregnancy.

      Yeah, Baby!

      Before you get to most of the features at the end of the book, we think it’s helpful to really understand the way the pregnant body works—and remember, it’s your whole body that’s pregnant, not just your belly. Woven throughout the book, you’ll see several major themes that reflect our overall view of pregnancy:

       • Your body is an amazingly resilient and adaptive piece of biological machinery. The size of your belly and the stretching of your skin aren’t the only changes that occur during pregnancy:Your insides are metamorphosing too. Your heart beats faster to make sure nutrients are pumped to the fetus. Your hormone levels fluctuate to prepare your uterus for growth. Your musculoskeletal system relaxes, giving you more flexible joints and more curvature in the back to prepare for carrying and delivering a baby. All these transformations mean that you may experience some unpleasant side effects (like constipation, for example). What’s interesting is that there’s an adaptive value to many of the symptoms of pregnancy, so that the nausea, breathlessness, and aching back you might feel, evolutionarily speaking, serve some value in protecting the growth of your child.

       • The goal of pregnancy isn’t just to deliver a healthy baby but to lay the foundation for lifelong good health for your child—not to mention that of his children and grandchildren. That’s the amazing thing about epigenetics. Once you see some of the long-term effects you can have on the health of your child while you’re pregnant, you’ll realize that it’s important to start this process with the end goal in mind. We like to call it reverse engineering.

      One of the ways that you can increase your chances for a successful pregnancy is to learn as much as you can about what’s happening, so you won’t be anxious. Simply educating yourself about what’s going on in your body is one of the smartest things you can do, because it allows you to roll with the punches rather than get KO’d by every little symptom or complication. In fact, staying calm during pregnancy has repeatedly been shown to have a positive influence on your child’s health.

      So we want you to take the pressure off of yourself and not to try to do it alone. The key is to have some support, regardless of whether you’re married (about 40 percent of children are born out of wedlock), in a relationship, or flying solo. Your mother, sisters, friends, or even the internet buddies you meet on pregnancy websites can all become part of your support system. One of the features that has always distinguished human beings is that pregnant women have relied on other women in their communities to support them. Today, social support has been linked to improved fetal growth. (Those cavewomen knew what was good for them.)

In a way, managing your pregnancy really comes down to one overarching goal: managing stress. We’re not just talking about stress management in the traditional bubble-bath kind of way, but in the big-picture kind of way. How does your body cope with the stress of housing and growing what’s essentially a biological hitch-hiker? How does your baby adapt to potentially stressful situations that
