One of my main tips for doing that is wearing a body compression garment. Something that cinches your waist back together again after you have the baby. If you keep everything held together, it's going to help your body's elasticity come back after losing the baby and all the weight. It's going to stop you from getting more stretch marks and damage to the surface of your skin. You're not going to allow your loose skin move around as much. It's going to help your rib cage and hips go back again.
