Like most things though, when you leave the kids alone, they seem to sleep just fine. They never sleep when you want them to, but they seem to have no problem sleeping on their own accord. See incriminating evidence below.

It would seem that there is a lesson to be learned here. There is always a lesson. Parenting is actually the best way to find out that you know nothing. It is a sure fire way to have any feelings of superiority yanked right out from under you. Children are smaller than us, not as smart or experienced, and less physically capable. Why is it that they can instantly make us feel so completely inept?
Like Little Boo Peep, who lost her sheep, if we leave them alone, we may just find that they end up doing what we wanted them to do in the first place. That's obviously not a hard and fast rule, but I've got to file this back in the folder for things Dad needs to think about on a regular basis.
Man, I'm tired. Where's my beanbag. I'm takin' a nap........
