How many ml's of expressed breast milk (not a formula)should a 8 and 9 month old baby eat per day?and how often?my baby's weight is 9 and a half kilo.

Calories : Your baby needs 950 calories a day and if your breast milk is average concentration at 20 cal per ounce then if it were the only source of nutrition you would need to supply 40 ounces per day or 1200 cc per day. By now most babies are on some solids and other fluids and not needing as much breast milk. And over time breast milk quality and quantity starts to vary. So feed until full !
