Am I expecting too much? He's never done it as a younger child & his 2 year old sister knows not to draw on walls. It just seems to be the latest in line of naughty behaviour that is really starting to get me down.
I've just gone completely nuts at him (it was 3 out of 4 of his bedroom walls) after a day of backchat, rudeness and insolence, it was the last straw. I always try not to shout and be angry mummy but I'd just had enough. Nothing seems to work with regards to his behaviour and I just don't know what to do.
Is this normal 5 year old behaviour?
