DS is 13 months - lovely, cheerful, affectionate, sociable little bub who seems reasonably alert etc.
And he hits himself in the head! Not hard enough to hurt, in fact last night he was hitting himself and going into gales of laughter, possibly partly at my horrified face.
I'm trying to be cool and suppress the PFB 'oh god is there something wrong' feelings.
Is this pretty normal? Or weird?
