Quick answer
A common general guideline is about 150 ml of formula per kilogram of body weight per day, split across feeds.
daily volume = weight(kg) x 150ml, divided by feeds/day

What if my baby wants more or less?
Babies self-regulate somewhat; consult your pediatrician if intake is consistently far outside this range.
