70-80 oz enough for stash?

I'm going back to work on November 9 and by then I should have between 70-80 oz of frozen milk as a stash.  Do you think this will be enough?  I don't pump very much at a time (usually 2.5-3 oz total), so I'm hoping I can keep up with how much she takes out of a bottle (usually 3.5-4 oz.) by pumping at work and throwing in some milk from my stash if necessary.
