Enough to build a stock pile?

Ka

Baby girl is 3 weeks tomorrow. I have 7 more weeks of maternity leave. She is exclusively breastfeed.

I have been pumping once a day at 5am and getting between 5 and 7oz total during at 17 minute pump session. If I only pump at 5am for the next 7 weeks, will that be a big enough stash to help me with growth spurts and such once I am back to work?
