From the moment your baby was born, you've enjoyed each noise and move he makes. You anticipate him reaching new milestones and will celebrate each one as it comes. Now that your baby is 3 months old, he should be able to stretch, kick, put his hands in his mouth, hold onto toys and raise his head and chest up when you place him onto his stomach, according to the American Academy of Pediatrics' website, You can stimulate further physical development by spending time and playing with him.

Step 1

Place your baby onto his stomach for play time to encourage him to lift his head and chest up, which will strengthen his neck muscles and give him more head control. This will also give him to opportunity to learn how to roll from front to back, too. Then he'll figure out how to roll from his back to his belly. Encourage him to roll to the side by placing a toy to his side. When he rolls over, praise him and smile to show him he's done something good, advises BabyCenter.

Step 2

Support your baby with your hands to help her stay in a sitting position, while she plays with her toys. You can also place pillows around her to support her, notes Doing this will help her learn how to stay sitting up and can help strengthen her muscles.

Step 3

Offer your baby bright-colored toys and rattles that he can reach for and grasp, recommends WebMD. Doing so will help improve your baby's hand-eye coordination. At this stage, your baby is starting to get more curious, and should be swiping for and grabbing things.

Step 4

Hold your baby and stretch her arms up and to the side. Grasp her hands and gently clap them together to encourage play.

Step 5

Lay your baby on his back on the floor. Hold onto his legs and gently move them to mimic riding a bicycle, advises KidsHealth.

Step 6

Give your baby free play time during the day. Place her in her crib or on a blanket on the floor. Undress her down to her diaper and let her discover her fingers and her hands. She'll probably stare at them and put them into her mouth. Watch as she realizes she has feet and tries to grasp them in her hands.
