How Your Donations Make a Difference

Every time you donate gently used baby and toddler clothes (NB–5T), you help:

  • Another family save money by accessing affordable, quality clothes.

  • Keep clothes in use and out of landfills, reducing textile waste.

  • Support circular fashion — extending the life of every little outfit.

  • Create community impact by connecting families who want to share, not waste.

We’re not just recycling clothes — we’re building a movement where families help families, and every small donation adds up to something bigger.
