My 11 month old is very communicative in terms of pointing and grunting for things. He also says 'mmmm' when he wants my attention, which I assume is him trying to say 'Mama' or suchlike. However, he has never babbled at all. No b's or d's etc etc. He will be 1 in 2 weeks time and is almost walking, pulling himself up, cruising etc. I'm worried there may be something wrong...should I be?
