Thank you for all the advise. When he is with me I am anal about DS going to bed on time, very rarely plays on the computer and if he does it is only educational games or club penguin! We have a wii, but again the games are played rarely and are just sporting ones and even though he has a nintendods again it is just games suitable for his age.
Thanks for the suggestion singingmum about what he sees on tv, he is very sensitive to what happens to other people. His teacher has said that he asks some really philosophical questions but is emotionally too poor to process the answers, if that makes sense.
My problem is that at his dads he stays up late and I am pretty sure that he is exposed to a number of less savoury aspects of film/life etc. DS is worried about dads smoking, and in fact got him a fake cigarette thing for fathers day. If I have a glass of wine or beer with a meal DS checks that it is no alcohol!! He's never seen me have more than 1 drink (not a huge fan of it)but has said that he has seen photos of me drunk! Assume that these are at dads and from when I was much, much younger.
In the summer he had a massive blow and I physically restrained him, and we have discovered that this does get the paddy over with quicker, it's just a question of being able to grab him quick enough. During that occassion he bit me on my wrist and I do beleive he had no idea what he had done because when he asked if he had hurt me and I showed him my wrist he burst into tears.
This latest do was kicked off my doing homework! We had talked about when things go carzy and one of them is when homework needs to be done. He had 2 parts and completed one without too much problem, but then the second part was too much.
DS says he doesn't want his dad to know because 'he'd batter me'. When I've asked about it he just says that he would clip him round the ear. I'm reluctant to go to gp as last time I went (DS wrote on the back of a card that he wanted to commit suicide, when he was 6)dad accused me of being like the modern media dragging up gossip that didn't need dragging up. It turns out that children who live down the road (at dads) had lost their dad (suicide) and he felt sorry for them, but I am not sure. Any way as I get on with dad I don't want to rock the boat, even thought I know I need to do what it best for DS.
Thank you for all your ideas and support, will keep working at it. x
