Thanks Mums, your comments have eased my mind considerably.

I think Tommy is definately the kind of baby who just likes to take things in, whenever he is put in a new environment he is very quiet and hardly moves at all. I guess this is his way of learning about things whereas other babies might explore.

I am truely thankful I have a happy and healthy baby I'm just a mum, like all of us, who will always worry I guess. #-o
