Hi all. I am trying really hard to sleep on my side, but I can't do it. I position myself that way and even put the recommended pillow between my knees before I fall asleep. Inevitably, I wake up on my back. I dutifully re-position myself, and fall back asleep. Of course, I wake up a few hours later on my back. At 12 weeks, this probably isn't a problem (or is it?), but pretty soon it will be. How dangerous is it to sleep on your back when pg? What if I can never train myself to stay on my side?
