How Long Is Too Long to Breastfeed?

Q&A on extended breastfeeding

Emily Oster

2 min Read

What are the benefits, if any, of “extended” breastfeeding? As someone who’s doing it at 10 months and not planning on stopping until we want to, is this doing my child any good (or any harm)?

––Breastfeeding for a long time

I want to start with the most important benefit of continuing breastfeeding: it sounds like you enjoy it and it is working for you. This is awesome, and it is the best reason to continue.

On your question about harm, there is no reason to think extended breastfeeding (even long past where you are now) causes any harm. Globally, historically, breastfeeding until the age of 3 or 4 wasn’t uncommon. As long as it works for you, it works. (One word of warning: it can be more difficult to wean an older child if they do not want to — it’s hard to set this boundary. You may have to get creative, like the friend I have who rubbed garlic on her breasts.)

In terms of whether it is doing your child any good — again, I’ll say first that if it’s time you enjoy together, then yes. In terms of the data, the most well-documented benefits of breastfeeding occur early on: benefits to NICU babies, a slightly lower risk of gastrointestinal illnesses in the first month. There is no plausibly causal evidence on longer-term breastfeeding. There are correlations with child outcomes, but they are all likely driven by differences across people who breastfeed for a long time.
Ultimately, I always come back to Dr. Spock’s advice on breastfeeding, which is that it’s something you might try since you might enjoy it! If it’s working for you, it’s working, and that’s enough.

💧 Is your kid drinking bathwater? Here’s the 411: It’s gross but not dangerous! Comment “Link” for my full guide to bathtime.

 A little soap or mold from toys isn’t harmful, and diluted pee is no big deal. Eating a lot of poop can make you sick, but in small amounts, it isn’t toxic.

Bottom line: Bathwater isn’t your kid’s best drink option, but don’t stress too much! Just keep an eye on them during bathtime for safety.

Why is it that schools always call mom, even when dad’s the one with more availability? Comment “Link” to dive into the data on inequality in parental workloads.

A study shows just how deep the gender divide runs when it comes to household labor—even in something as simple as a phone call. Does this ring true for you? Share your experience in the comments 👇

Ever seen a headline that makes your heart race, but when you dig deeper, the study behind it doesn’t hold up? That’s a panic headline! It’s designed to grab attention and spark fear, but the research it’s based on is often weak or irrelevant. Next time you see one, take a breath, look closer, and don’t let sensationalism get you stressed out.

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.”
