Ha ha.. what do you expect a two-year-old child to do? Read books!!! every child is different and some take longer to achieve a milestone. Just remember one thing... all healthy babies walk, talk, crawl, and babble... though some take longer than expected. Unless your baby has other health issues, don't worry unnecessarily.
