I just wondered if anyone had any experience of this. My dd is 20 weeks and until about 2 1/2 -3 weeks ago was starting to become very vocal and almost chatting to us although has never giggled. Over the last 2 or 3 weeks she has been very quiet and hasn't been smiling as much. I am a first time mum and a bit neurotic I admit but very concerned that she seems to be regressing... Am going to chat to health visitor about it tomorrow, my mum and husband tell me I am being ridiculous but I keep wondering if she has got a some sort of delayed development
