ParentData with Emily Oster

An announcement from Emily about the podcast.

For many people, when we start thinking about a family, we assume it'll just happen nine months from the moment we start trying. But that isn't the way it happens for all of us. And fertility can often be a journey that's more winding and more complicated and more confusing than we expected it to be. That's why ParentData has launched a new content vertical, Trying to Conceive (TTC), covering everything from ovulation windows to donor eggs to infertility treatments, along with a newsletter all about infertility treatment in particular, which aims to answer all of your questions with data. It's our mission to provide real evidence-based information so you can make the best decisions for your family. Today on ParentData, we're airing the audio from an event Emily did with three of the people who have contributed most to this trying to conceive content on parent data: Dr. Breonna Slocum, a reproductive endocrinologist and fertility specialist, Marea Goodman, a licensed midwife and author, and Dr. Pooja Lakshmin, a perinatal psychiatrist. This roundtable of experts discuss about where to start with fertility, answer audience questions in real time, and consider what they all wish that they knew before starting the journey of trying to conceive.

When you look at the data, it is true that after people have kids, marital satisfaction declines. Having a baby drastically changes everything in your partnership that was familiar, that was predictable, that you got used to. And some of those are the reasons you got into the relationship in the first place. That’s the reality of having kids. And as much as we love them, it can be an incredible shock to the system. There were date nights, there were lazy Sunday mornings in bed, and now there are feedings and diaper changes, feeling touched-out, packing school lunches the night before or at 5:45 in the morning. To paraphrase Ethan Hawke’s character from Before Sunset: We used to be in love. Now we’re roommates who run a day care together. Today on ParentData, we're joined by Dr. Yael Schonbrun, a clinical psychologist, an author, and a researcher who focuses on the science and data behind healthier, happier relationships. And she’s here to help you baby-proof your relationship. Take heart: for many — probably most — couples, this issue is not hopeless.

Shots are never a fun experience. Even if you are enthusiastic about vaccines, holding your kids as they get them is not usually a high point of parenting. And right now, the conversation about vaccines is increasingly fraught - and not just because our kids are sometimes afraid of needles. Because we're living in a moment where vaccines, long one of the most trusted and studied preventative medical treatments in existence, are suddenly being viewed with skepticism. Debunked theories about the relationship between vaccines and autism, for example, are taking center stage on Instagram and Facebook, but also in congressional hearings. Part of the problem is a lack of understanding. People don't know quite how vaccines work or why there are more now than in the past or how we can know that they are safe. Today on ParentData, we welcome Dr. Adam Davis. Adam is a pediatrician in the Bay Area, and he has a lot to say about vaccines from the perspective of someone who gives them. In the conversation, we talk about our theories on why the COVID vaccine sped up a slow-growing movement around vaccine skepticism, about the role that vaccines play in public health, about what it’s like for doctors to deal with vaccine skeptics in their own practice and what people can and can't be talked into or out of, and, because it’s a parenting podcast, some hacks for getting your kids through vaccines without too much drama.

In the last month, we've aired podcast conversations with Dr. Nathan Fox and Dr. Bapu Jena, and though the content is different, there’s an underlying thread that connects them both: what it means to deal with risk, and uncertainty. And not lose your mind. Economists deal with this constantly, and so do parents, but not in the same way. Economists learn not to panic in ways that parents, understandably, have a really hard time with. We’re trained to read the studies, and spot their holes, or their aims and impacts. Yes, we live in a world with trace amounts of lead in Cheerios, and sometimes it can feel scary to leave the house. But things that are low risk are low risk, no matter how scary they feel. Today on ParentData, Emily reads her recent article on risk and uncertainty aloud, and encourages us all to think about risk like economists, so that we can internalize it as sane parents.

For many of us, our first exposure to our pelvic floors is through the Kegel exercises we learned about in Cosmo, promising us great sex. The reality of our pelvic floors comes roaring back in pregnancy, when they are are more taxed than they've ever been. The pelvic floor turns out to have a hand in many things, including peeing, pooping, sex, pregnancy, labor, birth, postpartum, and menopause. And like with all muscles, the more we take care of them, they better they can take care of us. Today on ParentData, we welcome the Vagina Whisperer herself, Dr. Sara Reardon. Sara's new book, Floored: A Woman’s Guide to Pelvic Floor Health at Every Age and Stage, which will be released in June, explores the seasons of life with a pelvic floor, from puberty to menopause. In this conversation, we talk about the optimal ways to pee and poop. We discuss what actually happens when you go to pelvic floor therapy. We discuss Kegels and why they are often good but also not a panacea. More than anything, Sara takes something that we all experience privately, and encourages us to shine a light on it, take the stigma away, and tighten up with confidence.

Today on ParentData, we're welcoming back Dr. Nathan Fox, Emily's co-author for The Unexpected- a book about when things go wrong, or at least get complicated, in a pregnancy. Nate is an OB-GYN and a maternal-fetal medicine specialist, and he is one of our favorite returning podcast guests, not just because he’s a great talker but also because it’s really nice to have a doctor who can both provide medical answers to questions that come up around pregnancy, and help you have the best possible experiences with your own doctor. We’re discuss some big issues that arise during pregnancy and the many prenatal doctor’s visits; about the distinction between self-management and calling your doctor (when do you know if something is normal-bad or bad-bad?), and we’ll talk about just how subjective that line actually is. We also talk about risks and tradeoffs and about the kinds of postpartum issues that are worth addressing while still pregnant (we're looking at you, depression and anxiety). The Unexpected, and this conversation, are meant to help people be much better prepared for what they may face in their pregnancies and to help better navigate conversations with doctors — both the expected conversations and the unexpected ones.

Today on ParentData, we're airing an episode from Raising Parents, Emily's limited series podcast in partnership with The Free Press. The episode is the last in the series, but the first question we all need to grapple with before engaging with all the others: should you have kids? For most of human history, having kids wasn’t much of a choice. Social expectations, lack of birth control, and limited autonomy for women presented a couple of options: Have children, or join a convent. But the 1960s ushered in a big change. With better options for birth control and expanded career opportunities for women, many people for the first time could choose how many children to have, and whether they should have any at all. Fast-forward to today: More people are choosing not to have children for a wide range of reasons. Having children, of course, is a personal choice. But it’s a choice that has broader implications. Everywhere across the globe—the U.S., Europe, Asia, Africa—fewer children are being born. And strangely enough, having kids has become part of the culture wars. There are pro-natalist public figures like Elon Musk on one side saying everyone needs to have more kids now in order to save humanity. And on the other side, people like climate activist Greta Thunberg say rising sea levels are so catastrophic that having kids in this era is akin to genocide. But there’s no debate that the fertility rate is plummeting in America and around the world. Presently, American women, on average, have 1.8 kids. In the 1950s, it was 3. The replacement rate in the United States, which is the fertility rate needed for a generation to replace itself without considering immigration, is approximately 2.1 births per woman. Around the world, the fertility rate fell by more than half between 1950 and 2021, as many countries became wealthier and women chose to have fewer children. For economists like Emily, the speed with which the fertility rate is falling is cause for alarm. Economic growth depends, at least in part, on population growth. Retired people rely on generations of younger workers for support, through contributions to Social Security and taxes. With fertility rates in free fall, the math doesn’t add up. That’s the big picture. Now back to our own families, and a fundamental question: Should we even have kids in the first place, and what happens if we don’t?

Here at ParentData, we talk a lot about panic headlines. You know, the headlines that cycle through your feed about coffee and wine and sleep and lead and the causes of autism, many of which contradict the last panic headline, and almost all of them turning out to be not nearly as bad as they seem. But in the moment, they feel so scary and urgent. And if you're a parent just trying to follow the science, do what's best for your kid, sometimes it feels like you're being absolutely and really nonsensically bombarded with the wrong things to do. Today on ParentData, we've invited Dr. Bapu Jena to help us stay sane. Bapu is an economist and a medical doctor who specializes in natural experiments, which means observing human behavior in naturally existing behavior (as opposed to a randomized trial). This makes him an ideal person to talk about the uses and abuses of data, and how curious nerds conduct research that makes its long and winding way into a headline that almost feels like it's designed to scare the crap out of parents. We talk about the complicated relationship between causality and correlation, the academic and popular incentives to publish these kinds of headlines, and also who decides what research is worth sharing with the world. This is on the face a conversation about research, but really it's about reassurance - there are a lot of reasons behind publishing a story about lead in Cheerios that have nothing to do with you or how dangerous Cheerios actually are or whether you're a good parent who cares about the health and wellbeing of your kids. You are and you do. Don't throw out your Cheerios, but do explore the journey with us. Subscribe to ParentData.org for free access to new articles every week on data-driven pregnancy and parenting.

If you spend any time in parenting circles, it’s hard to avoid being inundated with “types” of parenting. Parenting labels are not neutral. Some are positive, some negative, but they’re never just descriptive. And lately, the most ink has been spilled over "gentle" parenting (also called permissive or respectful parenting). Gentle parenting, at its core, is an approach to behavior characterized by acknowledging a child’s feelings and not using punishments or rewards. But does it work? Let's see what the evidence says! Today on ParentData, Emily reads her recent article on gentle parenting aloud, digging into both the data, and also how hard the data is to evaluate.

The United States is one of the only countries in the world that doesn’t guarantee paid parental leave. We point out this fact a lot, but what does it really mean when a family doesn't have the ability to take time off when a baby is born? It means a lot of things. It means moms going back to work while still recovering from childbirth, it means parents struggling to figure out child care for their baby, and it often means babies going to group child care settings, which may be wonderful but do expose them to germs — germs that are more dangerous when babies are small than when they’re bigger. We can talk about these different challenges and why they might matter for kids’ and families’ outcomes, but to figure out how much they matter and in what ways...that’s what research is for. Today on ParentData, we're joined by Dr. Katherine Ahrens and Dr. Jennifer Hutcheon, who are both medical doctors and professors. They recently published a paper titled “Paid Family Leave and Prevention of Acute Respiratory Infections in Young Infants," an analysis of paid leave in New York State, and the impacts of that paid leave on hospitalizations for infants, mostly for RSV. The paper's bottom line is that paid family leave keeps babies healthier and keeps them out of the hospital, and now we have the data to prove it and to show that the effects are large in terms of numbers. But putting together a research paper like this is surprisingly tricky. You need to know what questions you’re asking, and you need to think about how you’re going to determine causality rather than just correlation. So we’re going to take their research from idea to final peer-reviewed paper, and we’re going to talk about everything you always wanted to know about how research is conducted.

Nutrition, along with sleep and screens, is one of the most contentious parenting topics there is. And questions about nutrition are particularly hard to answer with data, because disentangling correlation from causation is nearly impossible. What we eat is so wrapped up in everything else we do that it’s very challenging to point to a particular food or even a particular eating pattern and say that it’s healthy or unhealthy. But that doesn’t necessarily mean we know nothing. Today on ParentData, Dr. Robert Davis is here to talk us through what we do know. Robert is a medical doctor and an award-winning health journalist, and, most importantly, he’s a voice of sanity who realistically explores the nuances of nutrition, the food industry, childhood obesity, and how challenging it is for individual parents to try to parse it all. We talk about diet versus eating habits and the importance of language around that issue, food fads in the recent past and what we keep not learning from them, what Robert calls “nutritionism” (like obsessing about omega-3s instead of thinking holistically about our diets), whether ultra-processed foods are really as bad as we’re led to believe, kids and Ozempic, and how heavy a hand parents are supposed to take when it comes to their kids’ nutrition. This is a tough topic. We need to eat, we need to feed our kids, and we don’t fully process how stressful it is to feel responsible for our kids’ health and, as they get older, their body image. Hopefully this conversation can help alleviate some of that stress. Subscribe to ParentData.org for free access to new articles every week on data-driven pregnancy and parenting.

Today is Thanksgiving in the U.S., and after a fall – and a year – of divisiveness, could all use a holiday in which Americans are united in the task of consuming too much pie. More broadly, this holiday, more than really any other, is something Americans tend to do together. And so is parenting. Especially the beginning. The experience of having a newborn – the sleeplessness, the disconnection from reality, the wonder….it feels magical and unique, and yet also like a line connecting us to billions of people through the past. Today on ParentData, we're featuring an episode from another podcast, The Lonely Palette, that addresses this contradiction and the many others that just go hand-in-hand with parenting. It’s made by our producer Tamar Avishai; before she came to ParentData, she created this independent art history podcast, and this episode, about a 1970s feminist artist named Mary Kelly, felt perfect for the ParentData audience. Kelly meticulously tracked every data point from her son’s birth until age five (diaper stains, scribbles, first babbles, etc.) as a way of both coping with the lack of control mothers feel, and, just maybe, to try to hold on to something so fleeting. This episode combines Tamar's love of art history, Emily's love of data, and their shared love of parenting. Enjoy, preferably over another slice of pie.

We don’t all get to learn about vaginas in school or from our families or from creating a reputation as the "Vagina Economist." And quite frankly, this is to our detriment. But today on ParentData, we’re trying to make some progress on that. We're joined by Dr. Karen Tang, a minimally invasive gynecologic surgeon (think: disorders like endometriosis and polycystic ovary syndrome), who is tearing up social media with her women’s health education. Her book, It’s Not Hysteria: Everything You Need to Know About Your Reproductive Health (but Were Never Told), and it’s exactly what it sounds like — a user manual for anyone with a female reproductive system. In this conversation, we discuss how to talk to your doctor and how to make the most of your time with them, the lack of data on women’s health, why Karen feels strongly about reclaiming the word “hysteria” when it comes to health for women, and what it means to study women’s pain as opposed to...pain (?).

Pop quiz: what’s the only organ that you grow from nothing and then casually discard, that magically bosses around your hormones, and actually your entire body, and that is actually made up of two different people’s cells? Obviously it’s the placenta. Less obvious is how completely awesome it is. We're all wrapped up in this new baby on our chest, and since the placenta is so easy to deliver, relatively, and so gross to look at, we forget how incredible it is, and how absolutely crucial for the health of your baby. So today on ParentData, we’re going to finally give it its due. We've invited Dr. Gillian Goddard back for a mini episode to talk about all things placenta. We’re going to follow its journey through conception to pregnancy to delivery and - if you’re so inclined - beyond, and answer any of the questions you might have about this truly magical and sadly ephemeral organ.

When we talk about C-sections, it’s often prefaced with “unplanned” or “emergency.” About a third of all the deliveries in the U.S. are cesarean sections, and only about 16% of those are planned. And that leaves a lot of mothers in a position where they’re delivering differently than they planned or intended to. And in the U.S., a disproportionate number of those are being performed on black women. So how are we going to get to the root of what's going on? Today on ParentData, we're joined by Molly Schnell, whose paper “Drivers of Racial Differences in C-Sections” explores this phenomenon. Molly is an assistant professor of economics at Northwestern University and her paper found that black mothers with unscheduled deliveries are 25% more likely to deliver by C-section than white mothers. And she argues that implicit racial bias among providers or possibly even a financial incentive in hospitals to fill their operating rooms may play a role in this racial gap.

In the run-up to November 5th, it's easy to feel hopeless about the state of our national discourse, and what any single one of us can do to make a difference. That's when we need to look local, where it feels like things can actually change, and where the people who are trying to make the changes feel approachable but, often, no less inspiring. Today on ParentData, we're joined by Aly Richards, the CEO of Let's Grow Kids. They're on a mission to ensure affordable access to high quality child care for all Vermont families by 2025 - and they've actually done a lot of it. In June of 2023, the Vermont legislature made history by passing a first-of-its-kind, comprehensive child care bill into law, with overwhelming support from across the political spectrum. This bill supports child care through subsidies in both directions, to families and also to child care providers, and it provides a model for other states to hopefully follow. In this conversation, we talk about grassroots mobilization, about clipboards at county fairs, about knocking on doors and how important that is. We talk about the economics of change. We give the cold, hard capitalist case for child care and for child care subsidies, and explain how child care actually pays for itself, if you take a long enough perspective.
