I know the answer is different for everyone. This question is not intended to spark a debate but out of genuine curiosity. Since returning to work at 6 m PP my supply tanked and it's been a struggle to take measures to maintain it/bring it back up and balancing the need and desire to have quality time with my family/down time for myself when home.

If you pump/pumped/imagine pumping at work, how many oz at work would you have to get in order to justify pumping (let's say 2-3 sessions a day, 30 minutes away from desk each time.)
