sorry I'm with the pp, I wouldn't take teddy or stickers. taking stickers off isn't fair.

most kiddie are like that at his age. they need help, want help at home. its diff at kindy.

what motivates him? mini bribery helps and its not used forever. I give my 4yr acountdown and then say things like "come on, i'll help you tidy up and then you help me get our snack ready".
competitions to.see who can.get their part if the toys looking the nicest (winner gets a treat or a star)

if he's tired/ hungry etc then its all harder
