I've always wanted to be able to sleep on my side whilst hugging some kind of stuffed animal but to no avail. Ever since my SO gifted me a stuffed penguin toy that's large enough to fit in my arms and server as a pseudo-pillow, I've been loving sleeping on my side and have been really comfortable doing so too. I'm the middle spoon most of the time then. :D
I bought a body pillow (without the anime girl) for the same but within days I was in immediate pain come mornings. It was probably just overstuffed but I went back to front sleeping and it immediately disappeared
