Super Nanny said an hour in time out?! Are you sure?? We watch Super Nanny every now and then and she only recommends one minute for every year of their life and on a naughty stool, not in time out. Unless she's changed her methods? The footage we have watched recently is on Gem (or one of those channels) so they are old episodes I'm sure. But an hour in time out is far too long IMO.

Good luck. My 3 yr old is on our naughty stool right now (which is actually in our bathroom, on a kids plastic step) for the second time in 10 minutes!

ETA: sorry, everyone else had pretty much said the same as I did. We find the Super Nanny way pretty effective TBH. I think she's on TV on Tues or Wed at 8.30
