Pregnancy Insomnia!

Well, its 1:40am in the morning and I officially (literally as of today and figuratively as of my unable to sleep!!!) have entered into the last month of my pregnancy. Its an interesting time of being pregnant because all day (yesterday now) I could barely stay awake I felt so huge and exhausted. Playing in Finley's bed with him and his animals was a compromise for me to rest and still engage with my child. By 8:30pm last night I was passed out on my pillow, as passed out as you can get when you can only sleep on your L/R side...I'm a stomach sleeper :(
Finley woke up at 11:00pm with that cry-you know the one where he just needed a quick reassuring snuggle and to be tucked back in and then he was all better and back off into toddler sleep. Well, that was almost 3 hours ago and I'm WIDE awake still. I spent the first 2 hours just laying in bed not giving into the notion I wasn't sleeping. A pregnant mom of a 20 month old needs all the sleep she can find!!! Well, obviously that didn't work, I'm now sitting here with a bowl of cereal writing and watching a dog show on TV. EEEk...wreaking with anxiety about how tired I will be tomorrow once Finley wakes up at 6:00ish.
Biologically it doesn't make sense to have pregnancy insomnia. I had it with Finley as well and Ive had many friends with the same problem around this time. We all just tell ourselves "its in preparation for the sleepless night ahead of us" that's just crazy! I need to bank my hours of sleep so when I am up every couple of hours next month I don't pass out while nursing a newborn at 1:00am!
Here's to hoping to falling asleep soon...and not being a zombie in the morning.
