I am getting a bit worried about my DC3. He seems quite a happy, smiley sociable baby but doesn't really talk (although babbles a lot, copies expressions and sounds and says a couple of words). I'm not sure he understands as much as my other two did at the same age. Recently I've been trying to get him to identify photos of common objects in baby books (e.g "where's the banana?"), but he just doesn't seem interested. He'd rather play with the book, try and balance it etc than pay attention to what is on the pages. In general, he seems more babyish than DCs 1 and 2. He will fetch certain toys for me when I ask, but definately not every time. I know his hearing is fine because he sings lots of recognisable tunes very accurately. Just wanted some opinions really.
