As a busy parent, we're sure the last thing you need is an issue with fastening the diapers, Cheryl. Our diapers go through many quality checks, and we try our very best to make sure that each one reaches you in perfect condition. We're so sorry that wasn't the case with your recent purchase. If the tapes are not fastening as well as they should, popping open, or not re-fastening, the diaper may be too small around the waist. When fastened, the tapes should be in the middle of the picture strip on the front of the diaper. If the tapes will only go nearer to the end of the strip, it may be time to move up to a larger size diaper.We’d love an opportunity to help you with the diapers you were unable to use, as well as collect some details for our Quality Assurance Team. Please call us at 1-800-726-7377 at your convenience.
