What to Look For in Breast Milk Storage Solutions
- Material: BPA-free plastic, glass, or food-grade silicone
- Seal/leak-proof design: Secure lids are a must, especially on the go
- Stackability: Space in your fridge and freezer is precious
- Compatibility: Check if containers work with your pump or bottles
