For those mommas that full time and EBF how many oz does your baby eat while you are gone. I start work back in 4 weeks and did not start pumping until my little man was 6 weeks old. I have close to 100oz already stashed and he only nurses at the moment and i pump berween nursing.. what would be a a good amount to have stashed before i start back.

He will be 11 weeks when i start back
