The large part of this pillow wedges under your belly while the small part goes between your legs to make (left)side sleeping a little more comfortable. It pretty much did the trick but as I started to get bigger sleep got more and more uncomfortable and even the beloved Boppy wasn't helping. Then another lovely friend Sara Theisen lent me her pregnancy pillow, The Snoogle.
The Snoogle is a total body pillow. The hook end goes under your head and the other end goes between your legs. You can either face the long edge or let it line your back. I find it more useful to face the long edge.
So my nightly routine to get the best sleep I can...which still isn't all that great. I start out on my left side, body facing the long edge of the Snoogle in "running" position (thank you Bradley book...at least you were good for something...this means with your upper leg bent) and I typically fall asleep. After waking up two or three times and willing myself back to sleep instead of going to the bathroom (I'm not sure how much longer I will be able to do this as I get larger I will probably have to potty more than once a night) I get up, go to the bathroom and return to bed. I switch the Snoogle to face the other way, lay on my right side (I know left is better but my neck KILLS in the morning if I lay on one side all night) facing the long edge of the Snoogle. Its the best system I've got for now! I still wake up on my back from time to time but I just force myself to move back to my side. The things I do for this Baby Girl! ;)
