Swaddling is not always safe
DEAR DR. K: The other day I swaddled my niece before putting her down for her nap. My sister told me that’s dangerous. Really?
DEAR READER: Your sister is right.
To swaddle a baby is to wrap cloth (such as blankets or large towels) tightly around the baby, making it harder for the infant to move his or her arms and legs. Perhaps you have swad- dled your babies and with no ill effects. In fact, swaddling has been part of caring for babies for centuries. It makes a baby feel like he’s back inside the womb or being snuggled close. It calms many babies and helps them sleep better.
It also can really help some parents get their babies to fall and stay asleep on their backs. And that’s what pediatricians recommend to help prevent sudden infant death syndrome, or SIDS, which is more likely when babies sleep on their stomachs.
But there are downsides to swaddling. Because swaddling keeps the legs together and straight, it can increase the risk of hip problems. And if the fabric used to swaddle a baby comes loose, it can increase the risk of suffocation.
Although swaddling can help babies to sleep on their backs, that’s not what parents sometimes do. A recent study found that, when swaddled babies were put on their sides or bellies instead of their backs, their risk of SIDS went up a lot. The study can’t tell us exactly why the risk doubled. But one can imagine that a tightly swaddled baby might not be able to get her head up if she started having trouble breathing. And if that swaddling blanket came loose and she was face down, it also might make smothering more likely.
Here’s what parents should consider when they think about swaddling: ›
Always put your baby to sleep on his back. This is true no matter what, but is especially true if he is swaddled. ›
Make sure that whatever you are using to swaddle can’t come loose. ›
Babies’ legs need to be able to bend up and out at the hips for healthy development. If your baby is going to spend a significant amount of time swaddled, use a swaddling sleep sack that lets the legs move.
