Ds is 6 months, I have always been concerned, since I got pregnant, that he may have ASD as my brother has it and so does my uncle.
He makes eye contact, babbles, responds to his name most of the time, cries for me and DP if an unknown person holds him, is smiling since 3 weeks and laughing since hust before 3 months. He can roll and sit independantly.
However, when in his highchair or on my lap he bangs his head back quite a lot, he hand flaps and pulls his hair and I'm just mildly concerned incase these are early signs.
So when did you know and what were the first things you noticed?
