If my baby rolls onto his or her stomach during sleep, do I need to put my baby in the back sleep position again?
No. Rolling over is an important and natural part of your baby's growth. Most babies start rolling over on their own around 4 to 6 months of age. If your baby rolls over on his or her own during sleep, you do not need to turn the baby back over onto his or her back. The important thing is that your baby start every sleep time on his or her back to reduce the risk of SIDS, and that there are no soft objects, toys, crib bumpers, or loose bedding under baby, over baby, or anywhere in baby's sleep area.
