Freezer stash for back to work

Hey mamas,

I hope this is ok here, our guy couldn’t latch so I’m EP, but milk is milk right?

I go back to work mid May. Our LO will be almost six months by this point. I’m wondering how much frozen milk I need by this point.

I’m worried because I won’t be able to pump every four hours due to my work environment (outside). The best I can hope for is early am, on the drive to work, a lunch time pump (maybe), on the drive home and a couple of evening pumps.

I have an irrational fear of hurting my supply and having nothing for our nugget so I’m a bit panicked.

I currently have roughly 1920 oz stored and have run out of freezer (upright deep freeze) space. Should I buy a second freezer and keep going?

Suggestions, thoughts, experiences?
