He sounds pretty normal when I think of what Claire was like at that age. When Claire was 12 months old she could say mama, dada, bye and yeah. She did alot of grunting as well. She didnt really start saying many words till she was almost 18 months.
Only in the last 3 or so months (she is 22 months now) she has just had a bit of a word explosion and now can say stacks of words and now seems to be learning more words all the time. I've just been making sure I talk to her lots (she must be so sick of my voice by now!), tell her what I'm doing, I've been playing a game with her where we name her body parts and she has learned the names of quite a few of her body parts now, when she wants something and just points to it I tell her what it is called and after a few times she remembers and uses the word instead of grunting. Unfortunately she has recently learned "no" and knows how to use it... I have no idea where she got it from as we dont use no in our house.
