USA Diapers carries youth diapers in the common waist size of 18" - 28". This wast size includes many good products, including the Tranquility ATN (All Through the Night) disposable brief, which holds from 18.5 to 22 fluid ounces depending on whether you choose X-Small (adult) or Small (Adult). These small adult sizes can be used for children. The Tranquility ATN can hold more liquid than any other product on the market that fits youth sizes, and it is a quality brief. Made with side tabs so that it can be taken on and off more easily, this brief is perfect for overnight protection. If you are having trouble with leaking at night with your youth's current product, consider the Tranquility ATN for more absorbancy.
