I don't think the title of this blog actually exists. I think "pregnancy sleep" is an oxymoron - two words which have contradictory meaning. I don't believe any woman who is in her third trimester gets more than 2 hours of sleep at any given time.
I like to think of "sleeping" as dozing while trying to find a comfortable position. I constantly turn back and forth dragging my body pillow and all the sheets with me. When I say turn, I mean using a four point turn to get from one side to the other. It's a series of upper and lower body parts moving while grunting and expending way too much energy just to get to the other side of the bed.
Once I finally doze off the baby starts to move and kick my bladder which sends me to the bathroom. Then it all starts over again.
People have told me this is just Mother Natures way of getting me ready for the baby. I say Mother Nature is a bitch and I'm more than ready for the baby. Bring it on so I can get some sleep.
