Breast milk organization help

Hey ladies, my husband and I got a deep freezer to store breast milk and I can’t figure out the best why the organize the bags in the freezer. I saw on Pinterest to store them in 12 pack side boxes so they are in order by date but I can’t read the dates when they are in the freezer and the boxes don’t hold up well long. Plus I currently have 12 boxes full of milk and their bulky. I currently have milk to 3 freezers between my house and my moms but my son is starting his child care on Monday and I need to send breast milk with him so I have to get it under control and organized this weekend. Does anyone have any tips?
