My DS is 18 months old and so doesn't require much discipling at the mo - just a bit of a telling off and finger pointing when he starts a bit of minor tantrumming or throwing food around.
But for the future - and maybe this is being a bit premature because he may not need much disciplining (Fingers crossed!) but am just interested in finding out how other peoeple discipline their children. I have seen other kids throwing major, embarassing tantrums in supermarkets and would be mortified if mine did that. I have been wondering how I would deal with it. My current thinking is that I would lift him out of the trolley, take him outside and give him a real talking to - and deal with it properly when I got home. Just not sure though.
