That is it basically. I put him to bed and heard a noise upstairs - DH went to check what was going on and he had smeared toothpaste over the bathroom. It has been going on since he went back to school and has done it on sofa's, lampshades, floors. Nothing is sacred except for his toys. Our house is slowly turning an off white from all the toothpaste.
He is naturally chaotic and quite difficult and as soon as anything goes wrong will blame the nearest possible person - I know that he feels an injustice has been done a lot of the time. I am really feeling worried about this as it seems like his behaviour is regressing after we had such a nice Christmas together and everything is going so well for him.
I would appreciate some thoughts on how to stop this behaviour and how to encourage him to respect his environment.
