1 An 8-pound newborn drinks about 2 ounces at a time, roughly 10 times a day. 2  A 14-pound 4-month-old drinks 4 to 5 ounces at a time about six to eight times a day.  A 16-pound 6-month-old drinks 5 to 6 ounces at a time, roughly five times a day, in addition to eating some baby food.
Because of the great variability in the amount of solids that babies take during the second six months, the amount of milk will vary, too. One study found average breastmilk intake to be 30 oz per day (875 ml/day; 93% of total intake) at 7 months and 19 oz (550 ml/day; 50% of total energy intake) at 11-16 months.ifferent babies take in different amounts of milk; a typical range of milk intakes is 19-30 oz per day (570-900 mL per day). We can use this information to estimate the average amount of milk baby will need at a feeding: 1  Estimate the number of times that baby nurses per day (24 hours).
