DD is 2.4, very bright and articulate - also plenty of rather fiesty and defiant behaviour.
She knows right and wrong. But often if I warn her not to/to stop doing something - e.g. playing with her food, hitting baby brother, stamping on my toes, not doing as asked - she will think it is a game, laugh and do it anyway. The more I say no, the better the game. I feel rather impotent to do anything. I often feel like shouting, but realise it won't help.
Have tried naughty step technique, but not sure if it is right as she will sometimes take herself or other times come off step herself saying "sorry" like it is a get out clause.
Help!
