Better joint flexibility allows many 3-month-olds to wave and kick more forcefully and to open their fingers and bring their hands together. Even though your baby has been able to recognize you since he was just a few days old, he may now be able to show it. About half of babies this age begin to show an obvious recognition of their parents. Chances are your little charmer is still bestowing smiles on everyone he meets, but he’s getting choosier about the company he keeps. In large groups or with people he doesn’t know very well, he may need some time to adapt. –Baby Center–
Yup, the statement is so true. She kicks more forcefully and coos a lot when you talk to her. She’s really a charmer! Couldn’t wait to hear her first word!
