For my 4 month old boy, i take 1 scoop (scoop of Formula Milk) of EYS Brown Rice with 200ml of hot water and mix. Thereafter, boil it for 10 mins to completely cook the brown rice. The amount of water to put depends on how much milk your baby drinks. My boy drinks 170ml so i add additional 30ml for it to evaporate during boiling. Lastly, i add 5 scoops of formula milk to the brown rice mixture (5 scoop FM + 1 scoop brown rice for 170ml) and feed using bottle with a larger teat than FM because it's thicker. If you wish to feed via spoon then you might need to put 2 scoops of the brown rice to cook.
