Lately it seems like the only position Peter wants to have his head in is quite forward, almost so his chin is on his chest. I'm not sure if he is doing it on purpose, or if his head is actually flopping because he can't hold it upright. He usually has pretty good head control in general, and this has only started recently, so I am confused. I get quite worried when he is in the carseat and it happens, in case it restricts his breathing.

I am concerned that he might have some 'structural' damage from birth, when he got stuck.

Or is this normal??
