I know since I replied to this post I haven't been able to sleep right. I'm tired of sleeping on my left side and it goes numb and I wake up. I mean goodness what are we suppose to do. I toss and turn all night. I know the left is the best side but I might as well sit in a chair and go to sleep.
saw your comment about not being sure which side it is - its the left. i will have to look up in my book again to rememeber exactly why but it has something to do with nerves, blood flow etc, similar to why sleeping on your back isnt a good idea either.
i usually slept on my stomach and back too and ive been trying to get comfortable sleeping on my left side though am more comfy on my right. i use one pillow behind my back and one between my legs to keep me from rolling to my back or my right side. it seems to help.
I sleep on my back and prop a body pillow under my right side so that I'm kinda leaning to the left side. This seems to be the most I can lean to the left without staying awake all night long. Hope its fine :)
I think a bit later in pregnancy laying on your back will put too much pressure on your organs or something like that. I too was a stomach sleeper and have gotten used to sleeping on my side by hugging a pillow at my side. It does take some time to get used to and my husband had to move over closer to the edge to fit into our Queen size bed! I also read that there is one side you are supposed to sleep on and not the other, but I can't remember which side or why.
Well for me its feels better to sleep on my left side. I too sometimes wake up in the middle of the night on my back. I just turn on my side and go back to sleep. I also have a body pillow I put between my knees, you can also use a regular pillow.
