My DS has never been affectionate. If I pick him up he pushes me away (forcefully) and he never lets me cuddle him. When we are in a new situation he is quite happy to go off on his own and he never looks to me for reassurance. My friend's babies of a similar age are totally the opposite. I don't think he'd notice if I was replaced by a stranger. Is this normal? I feel like I'm doing something wrong.
