Milk Collection Best Practices

Safe Collection & Storage

  • Wash hands thoroughly before expressing
  • Use clean, sterilized pump equipment
  • Store in BPA-free containers or breast milk storage bags
  • Label every bag with date, time, and volume
  • Freeze milk within 24 hours of expressing (ideally within 4 hours)
  • Use a dedicated freezer or deep freeze section (0°F or colder)
  • Do not mix warm milk with already frozen milk

Creating Effective Listings

Tips for Great Listings

  • Be specific about quantity available (total ounces)
  • Include the date range of milk (e.g., "expressed Sept-Nov 2024")
  • Mention your diet and any relevant info (dairy-free, organic, medications, etc.)
  • Set a fair price (market average is ~$1/oz)
  • Specify if you offer local pickup, shipping, or both
  • Upload clear photos of your storage setup if desired
  • Update listings when quantities change
