I can't, because one of them always seems to be awake. Xander does not nap during the day, so he is usually asleep by 11pm or earlier on school nights. Connor is usually awake late. If he does fall asleep, I know he will be up soon for a feeding, so my body coniditons itself to stay awake for it. I am trying to change that. During Connor's naps, I cannot sleep, because Xander needs constant supervision. He is a wild child. Ironically, Connor went down for his first nap this morning minutes after Xander came down the stairs. It's like a sitcom at times where you just have to laugh about it.
