Even prior to pregnancy I slept with a pillow between my knees because I couldn't stand the feeling, it just hurt and I am not a big girl. Now that I am 3 months pregnant, I've had some restless nights. That all stopped (except for the 2am run to the bathroom!) once my wonderful husband surprised me with this pillow for my birthday! I have to admit, I felt like I was sleeping in a jigsaw puzzle, but it was an amazing sleep, one of which I didn't do the normal toss and turn. I reccomend this pillow to all women experiencing sleepless nights. And a big thanks to my wonderful husband for such a great gift!
