Anyone have a post party's belly wrap they highly recommend ? As a girl who struggled with eating disorders for years , I want to have it handy and ready to go so I don't have to look at my flabby tum. Also, when is it safe to start wearing it? Not sure if right after birth my body is too tender and traumatized. I wanna get small again but I wanna be safe and healthy for my baby :)
