Elspeth, thank you for your nice message. I know exactly where you're coming from and agree with you.
The no xbox/wii rule is because DS takes it to extremes. An hour or two is not enough for him especially if he has a new game and I can do without the constant moaning over Christmas. Also I really want us to spend some quality time together, playing board games doing jigsaw puzzles and listening to music, chatting, playing with toys etc.
DP has been really ill this year and has had to give up work, meaning lots of changes for DS. There is an odd power struggle going on between them and DS has been quite manipulative about getting my undivided attention. I think this is all a part of the changes - I doubt if you'd believe me if I told you how much energy and time I have spent on trying to get him to be excited about Christmas. The more I try the less enthusiastic he becomes. It is manipulation, I know.
I thought having his own TV might work because DP is suffering with depression and tbh it's not much fun for DS being stuck in the living room with him. We try to be out as much as possible but obviously I need to look after DP as well. DS only wants a TV in his room if he can have his own SkyPlus box to go with it. Don't worry, I did say no 
Oh, I am going on here and derailing the thread - sorry about that.
