He thinks its a joke when I say no or try to stop him from doing something naughty! And he seems to do it more when he gets the negative response.
For example- he likes to hit a wall hanging that we have over the sofa. He does it to get my attention if I'm not giving him enough. But sometimes he does it even when I'm with him and reading to him or playing with him. He'll then laugh and look at me because he knows he'll get told off or be removed from the sofa. It seems like any reaction is counter productive as he wants me to react to it!
I've tried saying no, putting on a stern voice/ face, trying to explain why he shouldn't do it, counting to three and confiscating toys, (am contemplating naughty step but will do it as a last resort).... Any ideas???
