I keep reading all these threads about pncy things that three year olds say. DS (3.5) can talk in sentences, knows numbers, letters, colours etc. But he not chatty as such - I am amazed by some of his friends and indeed most of the children I seem tor ead about on MN who seem to be having elaborate conversations about abstract concepts. DS can converse happily. But its usually restricted to topics such as how many more episodes of charlie and Lola or Dora he can watch or whats for tea or the attributes of aeroplanes (favourite thing).
