Boob Scoop: If your baby begins sleeping longer stretches, your body will adjust to produce less milk during those times. However, if initially the fullness is keeping you awake, it would help to manually express or pump to soften your breasts in order to relieve the fullness. Pumping to empty the breasts would not be recommended since it would keep milk production the same. It can take a few days or sometimes a couple of weeks for production to level off, but just be patient. Eventually your supply will regulate to your baby's needs.
