Congrats! Cofty is correct. What little sleep you get will be filled with dreams of getting more sleep.
Also, childbirth is a horrendous experience which I only experienced once before I realized that was enough. It wasn't magical or mystical. It just was plain old miserable.
Children rob you of sleep, time with your significant other and money. And they don't even bother to smile for the first month.
But, that first smile is so precious!
