Peanut is Putting Us Through Baby Training

Well, Peanut does not want to sleep at all anymore I guess. At least not at night. For the past couple of weeks she has been waking up in the middle of the night, hysterical. She runs to her door and yells for us, we put her in bed with us and most times she just sits there awake. She is very squirmy too so it is really hard to go back to sleep. The problem is, she is so tired from not sleeping at night that she takes like 3 1/2 hour naps at 2pm every day and then can't go to bed at night. I am praying that the new baby is a good sleeper because I have dealt with Peanut's inability to sleep like a normal human being since the day she was born.
I keep telling my husband that Peanut is putting us through training for the new baby. That we are getting used to waking up at all hours of the night and then putting ourselves back to sleep as soon as possible. But he tells me that he doesn't need any training. He KNOWS what to expect when the new baby is here and he doesn't need the practice right now. Always the optimist he is.
Yesterday was the best. Peanut went out for a while with her uncle and he took her to the park and the pet store. Then he was going to take her for ice cream but she fell asleep on the ride there so he took her home. I grabbed her and went to lay her in bed when she sat straight up and started chatting as if she never was asleep. The problem here is that when this happens, she thinks she has taken her nap for the day, even though she was only asleep for ten minutes. Then she fights me tooth and nail to take a nap for the rest of the day even though I know she is tired. She finally passed out at around 3pm and I had to wake her up at 5:30pm because I didn't want her going to bed at midnight. We put her to bed without a fight at 9pm, then she woke up at 1:30am and my hubby tried to get her to go back to sleep until 3:30am. Then I just yelled to put her in bed with us and she fell asleep until 6am. So that was pretty fun. She is just so off and I am off and we are all off together. And I know that in about a week things are just going to get worse.
