(always consult your doctor or midwife before doing so) The breast gel pads are designed to help offer relief from soreness associated with breast feeding, blocked milk ducts and engorgement.When heated, the breast pads can be used as a heat pack to help ease the flow of milk and blocked milk ducts. This can help reduce the amount of time needed for pumping or expressing. When frozen, the breast pads can be used as an ice pack to help offer relief from engorgement, pain from inflammation, mastitis, blocked ducts and overall discomfort that can be a result of breastfeeding. The pack can be heated or cooled.
