Will My Feet Return to Their Normal Size Postpartum?

Q&A on shoe size

Emily Oster

2 min Read

My feet grew while I was pregnant: one size up; my baby is 14 months now. Will they ever go back to pre-pregnancy size? They aren’t swollen anymore, just a size longer, so all my pre-preggie shoes don’t fit. Am I wasting my time holding onto them? I suspect it was the relaxin hormone with all the tendons between the bones in my feet and toes.

—Tanya

I am sorry to report that you are indeed probably wasting your time. I looked into this in detail, and I’m afraid your question is answered by the title of this paper: “Pregnancy Leads to Lasting Changes in Foot Structure.” 

The authors in this paper follow 49 women from pregnancy through five months postpartum. They find that foot size does increase during pregnancy. Interestingly, what happens is the arch gets less rigid, leading to a broadening and flattening of the foot, which often results in a need for a larger size shoe. These authors found that the foot size did not revert five months postpartum

I will say: this is only five months out! So maybe three or four years later, things will return to normal. Then again, maybe not. In the meantime, buy some nice shoes!

It’s been 27 years since my fourth and last baby was born. I have run three marathons (which can change feet!) and countless shorter road races. Went from a size 8 to a 9 or 9 1/2. Donate your too-small shoes and have fun shopping for new ones. (my new motto is “comfort over cute.”)

I’m nearly 4 years post-partum and while my feet did finally return to my usual size (was a half size up for around 3 years), I still generally need wide-width shoes now instead of my previous medium-width shoes. Possibly having to replace all of your carefully-chosen (and likely not cheap) footwear is one of the hidden costs of giving birth that no one tells you about!

I’m three years postpartum and still up a shoe size. I had to buy all new shoes. I delayed and crammed my feet into too small shoes hoping they would go back. Save yourself the pain! I’m pregnant again and terrified I’ll go up another size! I’m 5’ and wear a size 9 now. A 10 would be comical!

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.
