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. This move helps him strengthen the muscles he needs to flip.
Your baby may be able to sit unsupported with her back straight. This will free her hands for exploring, and she'll learn how to turn when sitting to reach for a toy (Sheridan 2008) . At this point she may even be able to get into a sitting position from lying on her tummy by pushing up on her arms.our baby will start to learn to sit at about the same time as she's managing to roll over and hold her head up. The muscles she needs to use develop gradually from birth, and she finally becomes strong enough to sit between four months and seven months.
