you should direct feed you baby so that supply will increase / maintain. if you always pump our, chances are, your milk supply will dip slowly and you won't have excess.
for me, i let baby latch on, then i pump after she has finished. the pumping is meant to stiumuate the breast / brain so that it will produce more...then i pump at night when baby is asleep or got up very early in the morning to pump, or both. all the EBM i kept in the deep freezer,.l
