I have a ritual and it's mostly because of my baby, haha. My ritual is very strange, but it actually works for me.

He's 17 months old and routin is very good for babies, and also good for me! It's pretty simple. When it's time for bed we put on jammies, go into the bedroom and I turn on Conan. My t.v. is hooked up to a laptop, we don't have cable in there, so I watch it on the tbs site whenever I want. My baby loves Conan (not sure why.) He even says "CoCo." LOL. For some reason, Conan not only helps my baby go to sleep, but watching the show ends temper tantrums.

I don't need to remind myself. The baby starts rubbing his head and eyes when he's sleepy. So, he's like my "go to bed" alarm for now.
