Want to keep tots warm on chilly nights without worrying about SIDS? Check out these cozy sleeping bags. They can replace loose bedding in the crib, which means baby will snooze safer (and hopefully longer). These are just a few of our favorite sleep sacks for sleepy babies.
New mamas often worry about SIDS, so removing fluffy blankets, bumpers and stuffed animals from a babe's crib is advised. Once your infant passes the swaddling stage, Aden + Anais's new breathable muslin sleep sacks ($35) can come in handy. Made of the same soft material their blankets are famous for, the lil zip bags keep lil ones from overheating. Available in darling designs, the sacks fit babes 6 months old through age two.
