How many Oz do you pump from each breast on each pumping session??

Johanna

So I chose the Medela swing since it was small and good to carry everywhere.

I am 15wpp and exclusively BF my baby boy.

I don’t know how much milk I was supposed to be extracting to have a good supply.

I can pump 4oz when my baby sleeps 7hs on the night but I don’t think that’s enough. How many oz you pump from each breast each time?

I am scared to dry out when I get back to work on May.

Pls help
