I used to have horrible nights. I couldn't ever sleep. I worried about everything and anything. I had to have prescription medicine to put me to sleep for longer than 3 hours.
Then we got married.
My Jacob falls asleep in 30 seconds. He literally counts aloud to as high as he can before he passes out. As soon as this happens and his breathing slows a bit, my awesomely schnozed hubs starts to snore.
It isn't loud. It isn't annoying. It's perfectly timed. It's basically a free sound soother.
