I am sorry that you are going through all this. I have to say that I agree with ALL Ellie's comments - both those about the children and those about letting go.
I also agree with your comments about TV's in the kids rooms - I would go even further and say avoid letting them all have PC's in their rooms - it leads to a fragmented family life style. Having said that - when I was a teenager I was out of the house from dawn until dusk when I could be, either with my friends or out riding the horses. When at home I would go to my room and either listen to music or read. To me it'a all part of the detachment and growing up process. I am not close to my parents and that does deeply sadden me, and I want my children to be closer to me than I am to my parents - but we can't make them be like that.
One thing that does really help is family meal times. We ALWAYS eat together as a family in the evening and share what has happened in the day. We never eat on our laps in front of the television.
