Is It Dangerous to Swaddle My Baby?

Q&A on a panic headline

Emily Oster

3 min Read

Hey Emily! I’ve seen some chatter on social media about new “evidence” that swaddling infants isn’t a good idea — thoughts? Has anything actually come out to make us rethink this practice?

—Swaddle-confused

Short answer: No, there is nothing new and concerning about swaddling.

Longer answer: Chatter about swaddling comes up frequently; the American Academy of Pediatrics has gone back and forth on recommendations on it, which can get confusing. The main question raised is whether swaddling might increase the risk of SIDS. The bottom line is that when swaddling is used correctly, there is no evidence for this link.

What we do know about swaddling is that it improves sleep. I talk about this in Cribsheet, and the evidence is quite good. Researchers bring babies into a sleep lab and use a combination of video and swaddles with sensors on them to observe impacts on sleep. What they find is that infants who are swaddled are less likely to make a transition from a startling and stirring to being more awake. In this way, swaddling helps infants connect periods of sleep, and makes for longer sleep sessions overall.

Swaddling should not be used once infants can roll, and infants should not be put to sleep swaddled (or unswaddled) on their stomach. This is a short-term, back-sleeping, solution for early infancy. Swaddling and placing an infant on their stomach has been linked to a higher risk of SIDS in at least some studies.

What you may have heard is chatter and concern that because swaddling helps infants sleep better, it might raise the risk of SIDS. This concern is largely theoretical, though. There isn’t data to support it. Moreover, since swaddling often makes it easier to have infants sleep on their back (because they sleep better), there may be substantial value here. A simple bottom line is that a swaddled infant put to sleep on their back is safer than a non-swaddled infant on their stomach.

The AAP guidelines on swaddling make sense to me. They specify that it isn’t a SIDS prevention approach, and that it should not be used once infants can roll, but that it can be a helpful practice. I will give the AAP the last word: “In summary, it is recognized that swaddling is one of many child care practices that can be used to calm infants, promote sleep, and encourage the use of the supine position.”

Looking for Memorial Day Weekend plans? Might be the perfect time to give potty training a shot. Potty training is notoriously difficult, and we unfortunately don’t have a lot of evidence-based guidance on what works best. So I asked the ParentData community to fill out a survey and share their knowledge — about 6,000 people responded.

👉Comment “Link” for a DM to an article that summarizes all of the best potty training advice we collected. 

Remember, you are not alone in the potty training struggle! It can be incredibly challenging, so please give yourself some grace.

Sun safety is a must for all ages, especially babies! Here are my tips for keeping your littlest ones protected in the sunshine:
☀️ Most importantly, limit their time out in hot weather. (They get hotter than you do!)
☀️ Keep them in the shade as much as possible when you’re out.
☀️ Long-sleeve but lightweight clothing is your friend, especially on the beach, where even in the shade you can get sunlight reflecting off different surfaces.
☀️ If you want to add a little sunscreen on their hands and feet? Go for it! But be mindful as baby skin tends to more prone to irritation.

Is side sleeping important during pregnancy? Comment “Link” for a DM to an article on whether sleep position affects pregnancy outcomes.

Being pregnant makes you tired, and as time goes by, it gets increasingly hard to get comfortable. You were probably instructed to sleep on your side and not your back, but it turns out that advice is not based on very good data.

We now have much better data on this, and the bulk of the evidence seems to reject the link between sleep position and stillbirth or other negative outcomes. So go ahead and get some sleep however you are most comfortable. 💤

My new book, “The Unexpected: Navigating Pregnancy During and After Complications” is available for preorder at the link in my bio!

I co-wrote #TheUnexpected with my friend and maternal fetal medicine specialist, Dr. Nathan Fox. The unfortunate reality is that about half of pregnancies include complications such as preeclampsia, miscarriage, preterm birth, and postpartum depression. Because these are things not talked about enough, it can not only be an isolating experience, but it can also make treatment harder to access.

The book lays out the data on recurrence and delves into treatment options shown to lower risk for these conditions in subsequent pregnancies. It also guides you through how to have productive conversations and make shared decisions with your doctor. I hope none of you need this book, but if you do, it’ll be here for you 💛

Exciting news! We have new, high-quality data that says it’s safe to take Tylenol during pregnancy and there is no link between Tylenol exposure and neurodevelopmental issues in kids. Comment “Link” for a DM to an article exploring this groundbreaking study.

While doctors have long said Tylenol was safe, confusing studies, panic headlines, and even a lawsuit have continually stoked fears in parents. As a result, many pregnant women have chosen not to take it, even if it would help them.

This is why good data is so important! When we can trust the data, we can trust our choices. And this study shows there is no blame to be placed on pregnant women here. So if you have a migraine or fever, please take your Tylenol.
