First 2 months, I use to pump out very frequent in order to get more milk.
I pump every 2.5hrs, is tired but it can make my flow better..
I remember some mummies mention before, should pump as your baby milk intake interval to avoid the supply is not enough when your baby encounter growing sprout.
Now I back to work, pumping session as below.
Total breast milk I can pump out is about 1liter per day.
My baby intake is about 800ml per day, so always have extra to store. (It makes my freezer full of breast milk)
