NY Hospital Policy As of Saturday, NY State issued an executive order requiring hospitals to allow one support person in labor, and the relevant hospitals in NY which were restricting partners have said they will comply. The rules allow support people only in triage, labor and delivery and immediate post-partum, they allow only one support person, and everyone must be gloved and masked. Partners with symptoms of COVID-19 will not be permitted. Still, this is probably a sigh of relief for many women near delivery.

New Pregnancy and Infancy Data There are a few new studies that have come out about pregnant women, infants and COVID-19. The largest of these is a study of 33 infants born to women with COVID-19 in China. In this sample, 3 of the 33 infants contracted COVID-19. Two of the three had very mild symptoms which resolved within a few days. The third had more severe symptoms, although this infant was born at 31 weeks of gestation so the symptoms may have reflected pre-maturity as much as infection. This is overall quite encouraging.

There were also two papers (here, here) published which suggested possible vertical (i.e. in utero) transmission of the virus. This transmission was suspected due to antibody detection in the infants. The total sample size between the two studies is 7 infants, so this is a small group and it is difficult to know when the transmission occurred. It remains possible that even in these limited cases the transmission was outside the womb. In addition, it is important to note that none of these infants showed any symptoms of COVID-19.

Fever A lot of women in early pregnancy have written to me to say they are worried about COVID-19 because of links between fever and neural tube defects (same reason you do not go into a hot tub). It is true that some data has seen links between early pregnancy fever and neural tube defects, but my read is the most reliable data doesn’t see this. I think the best study here — it’s large and followed women over time — focused on a cohort of 100,000 women in Denmark. The data includes about 8,000 women who had a fever during early pregnancy. They see no link with birth defects.

This is not a reason to be cavalier about the virus (or other illnesses like flu), but should be reassuring.

Cases in Kids The data continues to suggest COVID-19 is mild in children, and they also seem to be less commonly infected (although this may reflect more asymptomatic cases). Tragically, there has been one infant death and one teenage death in the US thus far, but put in context these numbers are small (far less than child deaths from the seasonal flu). Nicholas Christakis has a thoughtful (and long) Twitter thread on this topic, both some details on what we know and some speculation as to why.

Updated CDC Guidelines for School and Child Care

NO QUARANTINES!!!

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?

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.
