My 5 year old son has just set fire to the dining room. I was in the garden when he walked out of the house, I turned and saw 6 foot flames at the window! I didn't think and just tore back in, fortunately it was a box I was able to grab and throw outside, the only damage is a scorch to the fridge and back door and the house stinks (but at least I know the smoke alarms work!)
He won't tell me why he did it, he just says he doesn't know and he just seems to have no perception of danger, how can I get through to him?
