The ABC's of Safe Sleep

There are so many things for parents to research and learn before welcoming a new baby into the family. One of the most important things is safe sleep. Babies sleep a lot and there are a few steps to follow to make their sleep space a safe place.

Follow the ABCs of safe sleep: Babies should sleep Alone, on their Back, in a Crib. Let’s break these down:


Babies should sleep by themselves, in their own sleep space with no other people. Room-sharing is recommended but bedsharing is not. Keep pillows, blankets, toys, stuffed animals, and all other soft items out of the sleep space. Babies can use a pacifier in the crib if it is not attached to the baby, their clothes, or any part of the crib. If a pacifier falls out of their mouth, that’s ok.


Place infants on their backs for sleep. They will eventually learn how to roll from back to tummy and tummy to back. Once they can confidently roll over both ways on their own, it’s ok to leave them like that, but always place them on their back initially.


Use a crib, bassinet, or portable play yard with a firm, flat mattress and a fitted sheet. That’s it! The crib should not have bumpers of any kind, and nothing should be attached to the crib, such as a monitor or a mobile. Babies can sleep in a swaddle until they’re 8 weeks old and a sleep sack with their arms out after that.

Avoid letting baby sleep on a couch or armchair, or in another device like a swing or bouncer. Sleeping in a car seat is ok, but only while riding in the car. Babies should be removed from the car seat and placed in a crib once the trip is done.

As with any baby products, do your research, check for recalls, register your product, and read the manual before using a new or used crib, play yard, or other product.
