Help! My DS of 34 months has got into the habit recently of screaming at the top of his lungs when things don't go his way. Attempts to reason with him/calm him down are pretty much fruitless - it's almost as if he gets locked in the behaviour. We've tried ignoring the behaviour, reasoning with him, offering him rewards for good behaviour, putting him on the naughty step (he jumps straight off!), and yesterday (after several warnings) resorted to a light smack on the bottom which didn't affect the behaviour one jot and just left us feeling lousy and shell-shocked. We're at our wits end as to how to handle it...he's a great kid the majority of the time (aren't they all!) but the screaming seems to touch a raw nerve with me and I'm afraid I'm going to end up screaming back at him. Any suggestions?
