I have never done this and it strikes me as a bad and wrong idea, primarily designed to make women feel even crapper about post baby jelly bellies (or at least that is how it is commercially marketed).
There is an advert for an abdominal binder on another parenting forum at the moment. It made me feel very sad to see it,but I don't know if I am in the minority thinking it is the wrong message to send to new mums.
Has anyone done this? Is it even medically advised or beneficial?
