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.
If youâre just introducing tummy-time play, begin with a few minutes at a time, allowing your baby to get used to the new position. Some parents start tummy-time play for about a minute or so at 1 or 2 months of age, when babies can hold their heads up for a short time. Others wait until a child is 3 or 4 months old, when the neck, shoulder and torso muscles are stronger.
