DS (4) went to a birthday party and one boy was dropped off and the parent left (all the other parents stayed) he refused to join in, he kept running off on his own and hiding, he wouldn’t sit down with everyone to eat, wouldn’t eat anything (mum hosting had even bought different food especially for him knowing he is extremely fussy) he was clearly distressed the whole time and he kept hitting himself in the head. He doesn’t talk much and struggles with interacting. AIBU to think as a parent you wouldn’t leave this child to be dealt with by the host and other parents? I don’t know them very well because DS has only just started school but parents who’s kids went to the nursery said he’s always like this at parties, outings, play dates etc.
