Think nothing much to avoid except certain type.of medication. But i avoid spicy food.as whn i had wasabi, baby reject my milk. Lol... For increase milk, green papaya soup, fish soup, and drink PLENTY of water. I drink at least 3L everyday. Of course dribk as.much as you can to your comfort level. But at least 2L i heard. And keep latchibg helps alot to empty breast. And most impt, peseverance. My baby is on partial bf sonce birth. Most FM initially and i pumo bery.little. at 1 month i pump only 50mls 4hrly. But i still persevere on and decided to feed her breast milk as.much as.i can. Now at 10wks. We are on total bf !! its such an accomplishment! so jia you!
