Insomnia

Here I type at 5:27am. I've been awake for almost an hour just lying in bed tossing and turning. There's no baby awake, no pee-soaked sheets to change, no vomiting kid, just me awake and waiting for something to happen.
My body has been trained that it only needs a good 5 hours of sleep. I learned that during the newborn months. The baby now sleeps 10-12 hours a night but I only continue to sleep 5. Back when the baby was up every few hours I dreamed of how wonderful it would be when she slept all night. How ironic that now she sleeps and I can't.
I'm assuming I'll probably never sleep a full night again. Probably the next time I'm really tired, there will be a screaming baby or pee-soaked sheets or a vomiting kid. That's just the way this mommy thing rolls.
