As they gain better control over their hands, babies at this age love grabbing at objects and can even begin manipulating them with turns and twists. Activities that encourage hand-eye coordination will keep your baby engaged and learning how to interact with the world around them.

My Photo Album
Buy a small photo album and fill it with snapshots of your baby and the people in their life.
Give the album to your baby and tell him it's himself. Sit with him and show him the photos. Since his pincer grasp (with forefinger and thumb) is starting to develop, he’ll soon learn to grab the pages, and as he gets older he'll start to really look at the pictures and point at them.
He may react to familiar faces with excitement, or he might just be mesmerized by the parade of colorful images. 

Block That Move
Seat your baby on your lap, facing outward. Using a set of wooden or plastic blocks – ideally set upon a bare wooden or tile floor, for acoustic effect – build a tall tower.
Let her swat at the structure and reach for lower blocks. She'll not only enjoy watching the blocks fall, but if they're set on anything but carpet, she'll also relish hearing them crash.
Keep stacking them and letting her knock them down. She'll just get better and better at it, and you'll get faster and faster at the construction!
