Don't you hate it when you finally get the baby to sleep and you start stressing that somethings wrong. (Why is she sleeping so soundly? I did nothing different to all the other times... there must be something wrong!)
So you poke and prod the baby, trying to get some kind of reaction to indicate that it's alive and breathing and you wake the poor little thing. Then you spend the next 2 hours kicking yourself for being so paranoid only to do the exact same thing next time.
It's a vicious pattern!
