When I first met my 4 (nearly 5) yr old stepson he was 2...he seemed to be a normal child, speech was on track, he fed himself with no problem, was a happy child and interacted well with our other children. Now he is 4 and a completely different child. He doesn't speak and when he does it is gibberish, he wont walk flat footed only on tip toe, doesn't eat properly, he will chew his food for an unbeleivable amount of time but doesn't actually swallow it. When he comes to stay (which is every 2nd weekend) he doesn't interact with anyone and will sit watching tv for the whole time. When we speak to him it is like he has no understanding of what we have asked or how to respond. Things started to change around the time I had my last son and we assumed the quietness was because of the new baby but after 15 months he has gone backwards and is no longer the child he used to be. We have spoken to his mother about the problem everytime we take him home but she refuses to see that there is something "not right"...I have reached the stage where I am going to take him to the Dr anyway, even if she doesn't agree because as I said something just isn't "right". In our family we have 9 children combined (his, mine and ours) plus another on the way. My other stepson who is 10 lives with us and has aspergers so I was wondering if maybe this kind of thing runs in families.
