There are actually research finding linking screen time to disturbed sleep, for both children and adults. The link is especially strong for children who have TVs in their bedrooms. I would never have put a TV in my kid's room anyway, but the research is very convincing on that one all around.

I'm impressed that some of you have the patience to watch those kids' TV shows. Lord. Most of them make me want to gouge my eyeballs out. I feel relieved that DD's current school is not big on that kind of social currency. (Harry Potter is social currency, but that I can handle!) That IS how the experts say to do it, though--watch WITH your kid.
