Breast milk storage

Hana

Ladies, I was looking at breast milk storage options. I am hoping to breastfeed by day and bottle-feed (expressed milk) by night. I was considering investing in a 24 piece 4 oz glass container set. Intention is to use them now for breast milk storage and later for baby food. Containers are food sade, steralizer and freezer friendly. I will be on mat leave for 1 year and then back to work. Hoping to continue feeding my baby breast milk for 18-24 months.

Does this sound like a reasonable number or is it overkill?
