Question for exclusive pumpers since finding this information on the internet is rare... How old is your LO? How many ounces of breast milk is fed to your LO? How often do you feed?

Mine is 12 weeks old, he currently takes 3.5 ounces and eats 8 times a day, so a total intake is 28 ounces a day. I know the amount of ounces doesn't change in a day for a breastfed baby, but they usually start taking more during the day right?
