By now, your baby may be able to hold his or her head up for short periods, smile and laugh, notice his or her hands, follow objects across his or her field of vision, and make smoother movements. Some babies will even do a mini-pushup (using arms for support, lift head and shoulders while lying tummy-down).

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.
