I need a nap...

...and I have no reason for it! The baby has slept great three nights in a row, but have I slept--NO. What the heck is wrong with me and why can't I just sleep already. I really am tired. I really do want to sleep. I really don't need to be up every hour at night for no reason. Is this just a bad habit, have babies trained me to do this? And if so, how do I retrain myself. Sleep I love you, I miss you, come back.
