By now, your baby may be able to bear weight on his or her legs, coo when you talk to him or her, grasp a toy, and roll over from tummy to back. Some babies will even imitate sounds like baba and dada.
Of course, all babies are unique and develop at their own pace. If your baby was premature, keep in mind that kids born early usually need a bit more time to reach milestones. Talk to your baby's healthcare provider if you have any concerns.
