He's outside my "office" door now whinging & fiddling with the locked doornob because I won't play with him when he's not supposed to be at home. His keyworker says not to physically force him to go - which I can't physically do anyway when DP not home (which he isn't.) It's his final term there (he's 4 in August; school next Sept) and he used to go happily; but this has been going on for 2-3 weeks now. There doesn't seem to be any particular incident which triggered it. Any similar experiences? How did it work itself out?
