Easier to fall asleep

I used to take an hour or so after my head hit the pillow before I fell asleep. Insomnia? I guess, hard to self-diagnose. My cure, however, was to have a baby. I might not get as much sleep nowadays because of how early I have to get up now to watch her so her mom can get a patch of solid sleep, but the second I get into bed I'm in dreamland. I'll appreciate the benefits I get.
