Our DS, (3 years 5 months) has begun hitting other children at his nursery, without any particular reason. I've been spending a couple of nights away from home (at hospital) fairly regulary of late and wonder whether that could have unsettled him to that extent. Also when we got home today and I told him to get changed, he also hit me and started pushing me... How do we turn this behaviour round? At nursery they tell him that's it's not nice to do this. He seems to understand, but doesn't act on it... HELP
