or to their room.
My DCs are 3 and 5 and after really bad behaviour on a day out - constant low level stuff and immune to distraction, provision of toys, food, use of naughty step/time out, appeals to their better nature etc - I sent them to their rooms when we got home (at 4) and there they stayed for the rest of the day (allowed down to eat).
I mentioned this to my mum and she seemed to think I was a bit harsh. But they had their toys in their rooms, they were playing with them, and I didn't shout/smack/lock them in. I just thought it was a good way of marking really unacceptable behaviour, especially as all the stuff I'd tried while we were out had failed.
Is that a really old-fashioned punishment these days?
