Breast milk storage bags?

K

I have a freezer stash but it's all in bottles, and I've noticed that breast milk is taking over my freezer! I plan on buying a seperate deep freezer specifically for a BM freezer stash but I'm thinking that bags would be more convenient. Which bags do you mommas use or which ones do you like best? Are there any that I should avoid using?

Also, I have a few questions about deep freezers if you don't mind answering. Is an upright freezer a deep freeze or is it chest freezers only? Which is easier to store BM in and still last 6-12 months?

Sorry for all the questions, I'm just seeking some help! TIA 😊
