Work out how much infant formula a baby needs per day and per feed.
A common rule of thumb is about one hundred fifty milliliters per kilogram daily before six months, dropping to one hundred twenty after. Splitting the daily total across the number of feeds gives each bottle size. Bottle-fed babies can easily be over- or under-fed, so a weight-based daily target keeps portions appropriate and tracks appetite changes.
Formula Feeding Estimate
Total ml = weight in kg x 150 (under 6 months) or x 120 (6-12 months); per feed = total / feeds
Guidelines only; follow your pediatrician's advice and the formula package instructions.
