ds1 (4) has just started resisting pre-school. He is fine all the way there then gets emotional at the door. He's fine all day when he is there. He is being assessed for ASD and we have had problems like this before but only when it is accompanyed by other behavioural problems and other signs of stress. At the mo' everything is sweet, just this one thing. We've talked a bit about primary school - maybe this is causing it? any clues? or strategies for dealing with it. I've tried asking if anything is wrong and have so far got that he doesn't like playing Power Rangers with one boy coz he hits ds1 and he doesn't lik playing barbies. Nursery assistants always say he's had a good time.
