My 5 month 21 days old babygirl is not rolling over...just turning to sides....She is sitting with support.Do babies skip milestones?She is feeding well andotherwise active.

A. hello Your baby may be able to kick himself over, from his tummy to his back, as early as age 4 months. It may take him until he's about 5 or 6 months to flip from back to front, though, because he needs stronger neck and arm muscles for that maneuver.
