Frequently asked questions
How is the estimate made?
Formula-fed babies up to 6 months need, on average, about 150 ml per kilogram per day, up to about 1,000 ml per day. The total is divided by the typical number of feedings for the age.
What about breastfed babies?
Breastfeeding is on demand, without counting ml: the baby feeds whenever and for as long as they want. The World Health Organization recommends exclusive breastfeeding up to 6 months.
My baby doesn't finish it, is that a problem?
Every baby has their own pace and hunger varies from day to day. Follow hunger and fullness cues and your pediatrician's advice, who tracks weight gain.
