The belly bind moves because you move! This is also what helps to keep it soft and comfortable. Realize, the cultures that do this also practice postpartum “lying-in” which is a period after birth where the woman rests while she heals. If you are up and moving around constantly postpartum, the belly bind is going to shift, bunch, and roll. The only way to prevent this is to move less. Part of what belly binding does is encourage you to be down (whether lying, reclining, or sitting) and resting while letting others care for you!
