1 Red blood cell indices. 2  There are three red blood cell indices: mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). 3  They are measured by a machine, and their values come from other measurements in a CBC.

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.
So for an average 3-month-old baby boy who weighs 13 pounds, that would be about 32 1/2 ounces a day. The AAP also states that 'most babies are satisfied with 3 to 4 ounces per feeding during the first month, and increase that amount by 1 ounce per month until reaching 8 ounces.' Keep in mind that these are still averages, though, and some babies require more or less formula at each feeding and on each day.
