Once your baby has head control, and about the same time that he learns to sit on his own, he'll learn to roll over. He'll eventually learn to flip over from his back to his tummy and vice versa, and he'll use his newfound skill to get around a bit. The incentive for those early rolls is often an elusive toy â€” or you. Your baby may be able to kick himself over, from his tummy to his back, as early as age 2 to 3 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. At 5 months your baby will probably be able to lift his head, push up on his arms, and arch his back to lift his chest off the ground. He may even rock on his stomach, kick his legs, and swim with his arms. All these exercises help him develop the muscles he needs to roll over in both directions â€” likely by the time he's about 6 months old.
