Did you have a goal for your personal stash before you started donating?

I've been EPing since birth (DD is 11 weeks), and I have ~700 oz frozen. I want to donate via HM4HB, but I'm terrified I'm going to lose my supply randomly and then not be able to feed my OWN baby. But DH is worried about freezer space (we have a deep freeze, and can easily store 2000 oz + food)

Did you wait for a certain time frame? Wait until you had a certain amount stored? Or did you just go for it for the love of babies?

I'm so conflicted!
