I had breast abscess surgery when my baby was 1 month old.From then he is not taking breastfeeding directly.I am giving him BM by pumping and bottle feeding and also formula milk.But now my breast milk is reduced due to less sessions of pumping..But I want to increase BM.As I want to give my baby Less of formula milk and more breast milk. Can BM be increased by pumping???How to do it?? How many days it takes to increase supply??
