How to Choose the Right Adapter

Picking the right adapter is mostly about matching neck style and your usual feeding routine.

  2. Compare to photos: Use the product images to compare the adapter profile with your bottle's threads and rim.
  3. Think about routine: If you use a portable warmer often, choose an adapter that stays simple to attach on the go.
  4. Cleaning needs: Wipe or hand wash the adapter after feeds, and dry fully before storage to keep it sanitary.
  5. Plan for returns: If it does not fit, our 30-day return policy makes exchanging or returning straightforward.
