Though I am still in the quest of a milk booster that works for me, I have actually had one. In fact, all breastfeeding mothers have theirs - their respective babies! In my case, it's Achik-the-little-princess of course :-* Usually, I manage to express more on Monday, after a weekend of direct breastfeeding. So, mamas out there, please directly breastfeed your babies as often as possible :)
A total of 7 oz for the first session. 5 oz on other days.
