What happens when my baby begins to roll over? Eventually your baby will want to determine his or her own sleep position and may begin rolling to their tummy during sleep. Experts say this is normal – we want babies to learn to roll – and parents should not disrupt everyone’s much needed rest by continually flipping them back. You can rest more easy once you know your baby can roll both ways, back to tummy and tummy to back. Remember – lots of tummy time when baby is awake and playing! This will help strengthen your baby’s upper body muscles that don’t get used as much with the back sleeping position. If your baby is determined to sleep on her tummy, take extra care to ensure that there is nothing in the sleep area she can get her face next to and try and relax, knowing that you’ve done everything you can to protect your precious bundle!
