Maymom 3rd Gen Thread Changer or Bottle Converter - Wide to Narrow Neck by Maymom

by Maymom
  • 2x 3rd Generation Genuine Maymom bottle size changer includes an anti-leaking & anti slip o-ring; designed to avoid leaking when a mother bends over during pumping, reduced chance of a unscrewed bottle, no interfering with the duckbill, and easier screw on to both the wide mouth flanges and the standard-sized bottles
  • Allow Avent and Spectra S1 and Spectra S2 flanges to use with standard sized bottles like Medela bottles, Ameda bottles (narrow mouth) and original Dr. Brown Bottles (note will not fit wide mouth Dr. Brown bottle) to replace the wide mouth spectra bottles.
  • We recommend that you use a bottle-stand as well to reduce the tipping-over of the bottle.
