Head and neck muscles are the first to come under a baby's control. Muscle control moves downward, toward the feet. Babies typically roll from tummy to back first beginning at around 4 months of age and then back to tummy around 6 months of age, according to the A.I. DuPont Hospital for Children.
A: Rolling over is your baby's first big milestone on the road to getting mobile, and it usually happens around 4 months, but a little later or earlier is totally normal. At first your baby will only roll from his belly to back; this is easier because he can use his arms to help him take off. Back-to-belly rolling comes later, usually by 5 to 6 months, or a month after he learned to roll over initially. Your baby's first roll-over usually occurs during a tummy-time session. When placed flat on his belly, your baby instinctively uses his arms to raise his head and shoulders off the floor.
