breastfeed

Mga momsh, ftm here. Sa feb 26 pa ang duedate ko. As my baby grows, i wantbto give her 100% breastmilk. Paano po kaya yun, magppump na po ba ako ng breastmilf before lumabas si baby? And ill put it in refrigerator Or pagkalabas nya nalang. Kaso ngwoworry ako na baka wala agad akong mapump after I gave birth to my child. Need your advise and experience mga momsh
