Booby Tubes® from Earth Mama Organics are clever little, gel-free breast packs made with an organic cotton shell and filled with fresh, pliable flax seed. Use warm or cold, depending on your nursing needs. When heated, Booby Tubes® deliver warm, moist heat to tender breasts; when stored in the freezer they offer cooling comfort. Traditionally used to help ease breastfeeding discomfort, heat can help encourage milk flow, avoid clogged ducts, promote let-down and comfort the symptoms of infection, and cold is used to help reduce the swelling and tenderness of engorgement and weaning.
