what age do babies roll over

Babies typically start rolling over at around 4 months old, although it can vary. At this age, they will rock from side to side, which is the foundation for rolling over. They may also roll over from tummy to back. By 6 months old, babies will typically roll over in both directions. Its common for babies to roll over from tummy to back for a month or two before rolling over from their back to front. To encourage rolling over, parents can place their baby on a blanket on the floor with a toy or book to one side near them to reach toward with their arms. Tummy time is also important to help strengthen the upper body and neck muscles that babies need to sit up.
