Bottle is leaking from the plastic ring. Any recommendations?Updated a year ago

If milk is leaking from the sides, then it is most likely caused by misalignment of the ring. Please double check to see that the nipple and the outer ring (green or pink) are assembled properly, and then align the screw threads to tightly fasten the top and the bottom parts of the bottle. 

If none of these tips work, please fill out the contact form and we’d be happy to help you further.
