I find that when the television is switched off my kids are calmer and they play together better. I would say that keeping the television off as much as possible which can be hard with all the extra TV channels but persevere because it does make a difference as you are having to constantly talk above the noise otherwise and they probably can't comprehend what you are saying. Also I turn the electric off so the lights go out downstairs.when they won't go to bed. Then once they are upstairs they won't want to go back down into the dark
