How can I get to know my baby at four to six months?

Typical behaviors. The four to five month old will start rolling over from front to back. Better head control permits baby to watch people move around the room. Baby can push up and lift his/her chest off the floor. Objects can be grasped and let go for the first time. Baby may enjoy exploring different textures and colors. The sense of hearing is easily verified as baby turns to locate a voice.
