What Should I Do with My Remaining Frozen Embryos?

Q&A on fertility

Emily Oster

2 min Read

We’re in the process of deciding what to do with our remaining embryos. While I know you can’t tell me if I want more kids, there are practical questions I am still curious about. If I opt to implant another, I would like to do it in the next few months (for arbitrary age mindset reasons). That said, I wanted to nurse my 18-month-old until he’s 2 (also arbitrary, due to a sense of fairness, since I did that with my older kid).

So here are my questions: (1) Are there drugs in the frozen embryo transfer process that would legitimately interfere with breastfeeding? (2) Would breastfeeding, given my period has been back for 12 months, lower my chances of successful implantation? And (3) if I do have to defer implantation, is there any reason for me to stick to my “I don’t want to be pregnant after 40,” given they are eggs from a younger age?

—Two on Ice

I appreciate your pre-empting my speech about how I cannot tell you how many kids to have!

  1. The drugs that are typically used in these cycles could affect your breast milk supply. However, considering how far along you are in breastfeeding, the effects are likely to be small. It will certainly be recommended that you stop breastfeeding, though, just because we do not have much data about this situation. I realize this is not a very compelling answer.
  2. We can extrapolate the answer to this question from the question of getting pregnant while nursing in general. In general, breastfeeding acts as birth control by preventing ovulation. Breastfeeding is not contraindicated during pregnancy, including early pregnancy (i.e. implantation). So this is fine.
  3. No. In the immortal words of Matthew McConaughey in Dazed and Confused: “That’s what I love about these high school girls [read here: frozen embryos], man. I get older, they stay the same age.” You’ve got a little breathing room.

Reflux: It’s more common than you think! Comment “Link” for an article by @thepediatricianmom breaking down the information we have about reflux — what it is, what you can do, and red flags to look out for.

This graph shows how reflux changes with age. Nearly half of all babies experience reflux by 3 months, often peaking around 4 months before improving by their first birthday. And remember, if you’re struggling, you’re not alone. The most effective treatment for infant reflux is time. It will get better!

We’re heading into a three-day weekend, which means a lot of you might take the opportunity to do some potty training. 

Here are some things to keep in mind:
🚽 It takes longer than three days (based on the data!)
🚽 Your child will have trouble staying dry at night.
🚽 Poop sometimes comes later than pee – this is common, you just have to work through it.

Trampoline parks: great way to get the sillies out or injury haven? Or both? Comment “Link” for an article breaking down a 2023 study on injury trends in trampoline parks.

Here’s a visualisation based on the paper, showing the injury rate by area. Beware the foam pit and the high-performance areas! Slam-dunking, though, seems fine.

Screens have become a ubiquitous part of classroom life. Is this a good thing? Today on the ParentData podcast, I talk with @jessgrosewrites from the @nytimes. She recently ran a survey asking about kids’ screen usage after not being able to find studies and data on the subject.

“Nothing is all bad or all good. But I think overall, there just has been very little scrutiny into something that has been a massive shift in the way kids learn in the past, let’s say, two decades.”

We surveyed the ParentData audience and here’s what you said about the worst baby products. Bottom of the list: unnecessary warmers. Don’t get your kid used to having warm diaper wipes! Nothing good can come of that.

Comment “Link” for the best baby items and other parenting wisdom from the ParentData community. Best general advice: get things used, and you do not need as much as you think. 

Add your advice below! What do you wish you’d known about in advance, and what was a waste? ⬇️

How do we get our kids excited about math? Can every kid be a “math kid”? Shalinee Sharma of @zearnmath shares her insights on the ParentData podcast. 

When I offered her a magic wand to fix math education, she told me: “We have to pair understanding with memorizing. And the best way to understand really anything, but especially math, is simple pictures, concrete context, just make it feel real, not abstract and theoretical. What’s a negative number? Think about if sea level is zero and then you dive into the ocean, that’s a negative number. And then you climb a mountain, well that’s a positive number… We just need pictures to be a part of mathematics.”

Milestones. We celebrate them in pregnancy, in parenting, and they’re a fun thing to celebrate at work too. Just a couple years ago I couldn’t have foreseen what this community would grow into. Today, there are over 400,000 of you here—asking questions, making others feel seen wherever they may be in their journey, and sharing information that supports data > panic. 

It has been a busy summer for the team at ParentData. I’d love to take a moment here to celebrate the 400k milestone. As I’ve said before, it’s more important than ever to put good data in the hands of parents. 

Share this post with a friend who could use a little more data, and a little less parenting overwhelm.

I spend a lot of time talking people down after they read the latest panic headline. In most cases, these articles create an unnecessary amount of stress around pregnancy and parenting. This is my pro tip for understanding whether the risk presented is something you should really be worrying about.
