My 22 month old daughter hasn't started talking yet (she can say mama and dada but no other 'words'), she is happy and healthy (hearing has been checked - all fine), and does seem to understand most of what we say but it does still worry me as all the other children can say so much more. She's at nursery part time and when I am with her I do talk to her, read lots of books, and sing songs but I am concerned that I should be doing more to help. I would be grateful for anyone else's experience or advice as to what I could do to help her?
