Ds has been very slow on the uptake with speaking, he says "Mummy" and "Daddy" very clearly, but not much else. I really have no idea of how much he shouold be saying. My friends children of the same age all say a good few words, and one can even say a couple of simple phrases. DS has always been very active physically, he crawled before 6 months, and was walking at 9, do you think maybe he's just a walker and not a talker?????
