The long and short of it is that nursing pads are little pads that are put inside your bra between your breast and the fabric. You may leak milk in between feedings, and by wearing a nursing pad, it catches your milk rather than your clothing taking the hit. There are a variety of nursing pads available, and we will break them down for you so you can decide what kind would be best for you. http://www.cntopnurse.com/women-sanitary-products/nursing-pad/
