Types of Breast Milk Freezer Bags I Have Seen
I have noticed that breast milk freezer bags usually come in a few styles:

How I Choose the Right Size
I always think about how much milk I usually pump before buying. If I store smaller amounts, I go for bags with a modest capacity. If I pump more at once, I choose larger bags so I do not waste storage space. I also consider whether I want to freeze single-feed portions or larger quantities.

To keep my milk safe, I follow a few habits:
- I write the date on every bag right away.
