Its late and I'm still awake

So ask me why I'm still awake at 11pm when both of my kids are sound asleep and my hubby is going to bed in a minute. Thats because H was really up all night last night (as in she would fall asleep adn then wake up 15 minutes later crying) - so I was up basically all night. The only sleep I got was when Jay got up at 6:15am until 8am when he was getting ready to leave for work. So since my sister in law was here today I decided to take a nap since I was exausted... I went to sleep at 1:30 after finally getting H down for a nap. Next thing I know the clock in our bedroom says 5:05 and I am woke up by L coming in and telling me she wants to watch a movie. So yeah... I really slept for 3 1/2 hours this afternoon. Great for my tiredness... not so good for my being able to sleep tonight. So here I sit on the computer trying to get really tired so I can actually fall asleep tonight. (I discovered after H was about 2 months old and the extreme exhaustion wore off that if I take a nap in the afternoon I can't get to sleep the next night, so we will see how tonight goes.) and hopefully H will actually sleep tonight. She threw up while nursing tonight (not sure why she only throws up at night) but she doesn't have a fever anymore, so maybe she will just be so tired from last night that she will sleep all night. I know I need the sleep. So does J since H slept in our room in her swing last night since she was so sick. So he heard her every time I got up with her. Anyway I'm rambling... but I think its working cause I'm getting really tired. Good night
