The TV-Or Why My Kid Doesn't Sleep

After having my child for two almost three years now I've finally noticed a correlation between her sleeping habits and the TV. Contrary to what I would believe there does not seem to be any correlation between the total amount of TV she watches and her ability to fall asleep. The correlation happens between when she watches and when I want to put her down. I already had a sort of amount of TV limitation (nothing concrete), but recently I have enacted a time of day limit on TV and it has done wonders in our household.

1. No TV until after you are up and ready for the day (clothing on, hair done, teeth brushed, bed made)
2. No TV between lunch and nap time (Usually about an hour of time there)
3. No TV after dinner (About an hour and a half before bed)

It is amazing the difference in her ability to go down. With this and some other slight changes in her bedtime routine I have discovered peace in our home at bed time. So why did it take me so long to figure this out? Why the difference in bed time? Does the TV way over stimulate her for when she needs to sleep? I have no idea. All I know is that I'm so very happy with the result.
