For example, if his sister makes a 'sculpture' in her room and asks him not to touch it, he will immediately jump on it. If he is asked not to play with the lights in the car, the first thing he will do is to play with the lights. He's generally in a ...mischievous phase at the moment but responds fairly well to warnings and then naughty step type responses for other 'naughty' behaviour. This thing of doing exactly what he is asked not to is just harder to manage (and totally maddening as he is doing it so much) and I wondered if any one had any tips??
