any pregnant and breastfeeding mummies took milk boosters and it actually helps with the supply? if yes, can share what are the boosters you took?

It varies for different people. What works for me may not work for you. Oats and chia seeds work for me though. Usually will take oatmeal with frisomum for breakfast and in between meals if hungry. Chia seed is to make it as drink. You can try lactation cookies available at kiddy palace too. Taste wise is quite nice.
