What month do a infant start rolling on side to sleep?

Milestones: Once your baby has head control, and about the same time that he learns to sit on his own with support, he'll learn to roll over. There is no "exact" age for this, but usually around 6 months, a child may start to roll over. To assure the child is not on his stomach asleep, if concerned for suffocation, etc. they do may "wedge pillows" that prevent the child from rolling over onto their stomach.

Seven: seventh month. Variations are common.

Accident/purposeful: Infants may flip occasionally from birth and fully roll with a purpose by 4 months. It has been found that side sleeping is just as risky as belly sleeping with relation to crib death. Always put them down to sleep on theit back, and re-position them if they roll to the side until at least 4 months.
