About these numbers: Figures are population averages built from commonly cited pediatric
feeding guidelines (rapid stomach-capacity growth in the first days, then a plateau of roughly
750–900 mL per day from about 1 to 6 months, gradually easing as solids are introduced after
6 months). Real intake varies with body weight, appetite, growth spurts, and whether a baby is
exclusively or partially breastfed/formula-fed. This tool is for general information only —
it is not medical advice. Always confirm feeding amounts with your pediatrician or a
lactation consultant, especially in the first weeks of life.
Day-by-day and week-by-week values between these published anchor points are estimated by linear
interpolation, since most sources publish ranges for broad age bands rather than a figure for every
single day.
