We're sorry to hear you experienced leaks and the diapers feel cheap. We go through many quality checks to ensure the best diapers. Size and fit are a huge part of finding the right diaper for your baby that will have no leaks. Our diaper sizes are organized by weight, and since no two babies are the same shape, you will notice some overlap between sizes. In most cases, your baby should be within the weight range for the size you are using, but we've found that about 30% of babies are in the wrong diaper size. Please call us at 1-800 726-7377, and we're happy to help you and make a recommendation.
