How to Swap to Non-Toxic breast milk storage products:
Here's how to swap to non-toxic breast milk storage products:
What to know about breast milk storage
Breast milk storage bags and containers sit in direct contact with your baby's food, so the material they're made from matters. Welpr focuses on what these products are made of, whether that's glass, silicone, or plastic, and checks that materials are clearly listed and free from unwanted additives.
- Glass is the gold standard because it doesn't leach anything into milk, even when frozen or warmed.
- When plastic is used, Welpr checks that it's free from BPA, phthalates, and PVC, which are common in lower-quality storage products.
Check what you already have
Look at the breast milk storage bags or containers you currently use and check the packaging or product listing for material details. If a brand doesn't clearly state what the product is made from, that's a reason to pause.
- Look for labels that say "BPA-free," "phthalate-free," and "PVC-free" — if any of these are missing, consider replacing that product first.
- If you use plastic containers, check the bottom for a recycling number — avoid #3 (PVC) and #7 (may contain BPA) unless labeled BPA-free.
Use your current storage more safely
If you're not ready to replace your breast milk storage right away, small changes in how you handle it can help. Avoiding heat with plastic is one of the simplest things you can do.
- Never microwave breast milk in plastic bags or containers — thaw in the fridge or under warm running water instead.
- If using plastic containers, avoid pouring freshly expressed (warm) milk directly in; let it cool slightly first.
Choose cleaner replacements
When you're ready to switch, look for breast milk storage made from glass or food-grade silicone. If plastic is the most practical option, choose products that clearly list their materials and confirm they're free from BPA, phthalates, and PVC.
- Glass bottles with silicone sleeves work well for storing and warming milk, and they last through multiple children.
