The progressive compression massage from the chest wall forward has been thoughtfully designed to mimic hands-on pumping, a technique recommended by lactation experts to increase the efficiency of your breast pump. The massage allows the breast to be fully emptied, which results in an increase in the volume of milk expressed and a reduction in the occurrence of breast pain associated with clogged milk ducts, breast engorgement and mastitis!
