Roundup: Pregnancy Updates

Updates since Expecting Better

Emily Oster

5 min Read

It seems a very long time ago that I conceived of Expecting Better. I was thinking about that the other day and dug up the first email I sent, almost at random, to my now agent with my initial, slightly shaggy book proposal.

I said: “This brings me, finally, to the basic idea, which is a book which covers decision-making during pregnancy, focusing on what the medical literature actually says about risks, procedures, etc. I do not think this type of book exists. There are a lot of books about pregnancy (obviously), many of which go through recommendations on behaviors, and some things on decision making. I have yet to find one which actually presents any evidence.

I sent this email in February 2011; Penelope was born in April. I’m not sure what I was thinking in committing to writing a book during that first year, but anyway here we are.

Expecting Better has undergone a number of revisions, the largest of which I did just last year. With each of them, I’ve gone back to consider what the new data says, whether there are topics missing, whether there are changes in the way I want to talk about various issues. With the latest revision, I’ve gotten a chance to put many of the updates in the newsletter. So the roundup below pulls together most of the pieces I’ve updated over these past years.

Before we get into it, though, let me try to answer one crucial question that I get all the time, which is not addressed in any of the editions of Expecting Better: Does eating dates make you go into labor?

If you aren’t heavily into the world of fruit-induced labor, you may wonder why on earth eating dates would have anything to do with childbirth. Yes, they are a delicious sticky fruit, but so are figs, mangoes, prunes, and more. Why dates?

There are various theories you’ll see thrown around — something about hormones, or vitamins — but the answer to “why dates?” really lies in a few papers that argued that, for whatever reason, dates seemed to prompt labor. Perhaps the best-known is a 2011 paper that compared 69 women who consumed six dates a day for four weeks with 45 women who did not. The study wasn’t randomized, but the authors did find that a much larger share of the women who ate dates went into labor spontaneously (96% versus 79%) and that their labor was less likely to need augmentation.

The conclusion of the paper was that the finding warranted a randomized controlled trial. And following that, there were a number of them. This study randomized 77 women into a seven-date-a-day group and 77 others into a control group. It found that the date group did have less need for labor augmentation but were no more likely to go into labor spontaneously. A second paper with a similar-size trial found date consumption leading to shorter labor. A third randomized trial showed the date consumption group had more “cervical reopening” (i.e. more movement toward progress in labor) than the no-date group.

What to take from this? I would say good news and bad news for the date-labor plan. On the downside, if you are past your due date and your hope is to down a giant pile of dates to encourage labor, that is not likely to work. (Also, eating that much dried fruit all at once is a mistake for other reasons.) On the plus side, this actually does suggest that eating a smaller number of dates regularly over the last weeks of pregnancy might make labor slightly smoother. These effects aren’t huge, but they seem consistent. Perhaps worth a try

Roundup of other updates

Here are a couple categories of updates. Some of these made it into the new Expecting Better edition, some didn’t. 

Posts about “Can I have [fill in the blank] while pregnant?”

Posts about prenatal care (and birthing choices)

As a final note, I would be remiss not to recommend that you read this post on how it is totally fine to sleep on your back if you want to while pregnant.

Enjoy!

The AAP’s guidelines recommend sleeping in the same room as your baby “ideally for the first six months.” However, the risk of SIDS is dramatically lower after four months, and the evidence in favor of the protective effect of room sharing is quite weak (both overall and even more so after four months). There is also growing evidence that infants who sleep in their own room by four months sleep better at four months, better at nine months, and even better at 30 months.

With this in mind, it’s worth asking why this recommendation continues at all — or at least why the AAP doesn’t push it back to four months. They say decreased arousals from sleep are linked to SIDS, which could mean that babies sleeping in their own room is risky. But this link is extremely indirect, and they do not show direct evidence to support it.

According to the data we have, parents should sleep in the same room as a baby for as long as it works for them! Sharing a room with a child may have negative impacts on both child and adult sleep. We should give families more help in navigating these trade-offs and making the decisions that work best for them.

It was an absolute pleasure to be featured on the @tamronhallshow! We talked about all things data-driven parenting and, in this clip, what I call the plague of secret parenting. To balance having a career and having a family, we can’t hide the fact that we’re parents. If mothers and fathers at the top can speak more openly about child-care obligations, it will help us all set a new precedent.

Invisible labor. It’s the work — in our households especially — that has to happen but that no one sees. It’s making the doctor’s appointment, ensuring birthday cards are purchased, remembering the milk.

My guest on this episode, @everodsky, has come up with a solution here, or at least a way for us to recognize the problem and make our own solutions. I’ve wanted to speak with Eve for ages, since I read her book Fair Play. We had a great conversation about the division of household labor, one I think you’ll get a lot out of!

Prenatal vitamins 💊 If there is any product that seems designed to prey on our fears, it’s this one. You’re newly pregnant and you want to do it right. Everyone agrees you need prenatal vitamins, so you get them. But do you want to be that person who just… buys the generic prenatal vitamins?

Good news: fancier vitamins are not better.  Folic acid is the most important prenatal ingredient. Iron (with vitamin C) and DHA are also nice to have. Other included ingredients have only weak or no evidence to support their use. (If you do not consume animal products, add B12, plus a few others depending on your diet.)

Vitamins are just vitamins. Any prenatal vitamin that contains these is enough.

When it comes to introducing your newborn to the world, timing matters. It’s a good idea to minimize germ exposure in the first 6-8 weeks; after that, it’s inevitable and, very likely, a good idea! This doesn’t mean you need to be trapped inside. The most significant exposure risks are from seeing other people at home — family, etc. These interactions are not infinitely risky, but they do pose more risk than a walk or a trip to the grocery store, since they involve closer interaction. Think simple and make sure everyone is washing their hands before holding the baby. 💛

The first edition of Hot Flash is out now! Comment “Link” for a DM to learn more about the late-reproductive stage.

There are times when we expect hormonal shifts. Our reproductive lives are bookended by puberty and menopause. We discuss those changes often because they are definitive and dramatic — a first period is something many of us remember clearly. But between ages 13 and 53, our hormones are changing in more subtle ways. During the late-reproductive stage (in your 40s), you can expect a lot of changes in your menstrual cycle, including the length and symptoms you experience throughout. It’s an important time in our lives that is often overlooked!

🔥 Hot Flash from ParentData is a weekly newsletter on navigating your health and hormones in the post-reproductive years. Written by Dr. Gillian Goddard, Hot Flash provides all of the information you need to have a productive, evidence-based conversation about hormonal health with your doctor.

There are plenty of reels telling you how to parent. Plenty of panic headlines saying that “studies show” what’s best for your kid. Even good data, from a trusted source, can send us into a spiral of comparison. But I want you to remember that no one knows your kid better than you. It’s important to absorb the research, but only you will know the approach that works best for you and your child. 💙

Now tell me in the comments: what’s a parenting move you’ve made recently that feels right to you?

Let’s talk about sex (after) baby! Today on the podcast, I was lucky enough to speak with @enagoski about her new book on sexual connection in long-term relationships. Especially after having kids, this is something many people struggle with. Emily tells us to stop worrying about what’s “normal” and focus on pleasure in its many forms.

Ever wondered if you can safely use leftover baby formula? 🍼 The CDC says to throw out unused formula immediately because of the risk of bacterial growth. However, research suggests that bacterial concentrations do not appreciably increase after 3, 12, or even 24 hours at refrigerator temperatures. Good news! This means there’s not a strong data-based reason to throw out formula right away if you store it in the fridge.

Comment ”link” for a DM to learn more about tongue ties 🔗

Breastfeeding is often difficult, especially at the start. For babies with tongue ties, many infants (and their moms) struggle to get the hang of a good latch. This can lead to painful nipples and to inefficient feeding, and then low weight gain.

So what does the data say about the increasingly common practice of cutting tongue-ties in infants to improve breastfeeding success? Several weeks ago, @nytimes published a long and quite scary article on this topic.

After diving into the data, here is what I found. There is limited evidence that frenotomy procedures improve breastfeeding efficacy and the harms of the procedure are minimal. Many women do report that it alleviates pain and helps them with breastfeeding. However, it should not be a first-line treatment for breastfeeding problems.
