What Do You Use For Your "Bellies"?... I guess this is more of a question than a story to fellow "preg dressers," but anyway, what do you use for your "bellies"? I use a smaller square pillow that is wrapped up in two thinner blankets.
I guess the reason I am asking is because I want to know what else I could use to make me look more natural and/or round
