I'm not very good with discipline. Perhaps we are lucky, because Harry is generally pretty well behaved. He's never done anything really naughty, and if he has it's been our fault anyway (like the time he put the digital camera in the toilet, that taught us not to leave small, expensive items lying around near babies!). Of course, like all toddlers he has his strops if he doesn't get what he wants, but generally I just leave him to whinge to himself for a bit, and he'll gradually move himself closer and closer to me until we end up having a cuddle, then a few minutes later it's all forgotten.
I don't think that I've ever even shouted at Harry, only if he was about to do something dangerous. Even if I raise my voice he gets upset and hides behind his hands and I end up feeling bad and giving him a cuddle anyway. I do try to be consistent though, and if I've said that he can't have or do something then I don't give in. I'm also very good at ignoring him - if I ask him to come over so I can get him dressed and he runs off, I just let him run about without giving a reaction and he soon comes back!
We've never even used a naughty step. I have a friend who visits with her son the same age, and she uses the naughty step very effectively. Harry has therefore seen the naughty step in action a couple of times, and it has made such an enormous impression upon him that we can now threaten the use of the naughty step to stop him doing something, without him ever having sat on it!
Mia is crawling about everywhere now so it's time to start with the 'No' word. Like Harry, she has learned very quickly which things she isn't allowed to touch (sockets, radiators, the television and so on). This doesn't mean that she doesn't try her luck though. I love how she heads for something that is out of bounds, then looks back over her shoulder in anticipation, and just to make sure that I'm paying attention! It's also funny to watch Harry copy me, giving her a stern 'No' when she picks up one of his toys!
Sometimes I wonder if I'm too soft. Does everyone else use a naughty step with their toddler?
