(Younger babies with smaller tummies take less milk.) Breastfed babiesâ milk intake doesnât increase from months 1 to 6 because their growth rate slows.4 As growth slows, breastfed babies continue to get bigger and heavier on about the same daily milk intake, averaging about 25 ounces (750 mL) per 24 hours.
If we do the math, then, an average baby eats 9,125 ounces of milk/formula during their first year of life. To determine the cost of formula, I again turned to statistics provided by Kelly, who said the average cost of an ounce of formula in November 2005 varied from a low of $0.07/ounce to a high of $0.31/ounce.reastfeeding requires 400 to 500 extra calories for the mother per day. This is around one extra meal per day, or 33% extra food per month of breastfeeding. This is still probably less expensive then formula, but it is not as much of a windfall as you thought.
