There are a few products for youth that have wetness indicators. Youth refers to older than a child going through potty training and younger than the sizes for normal adult briefs. Youth incontinence can be caused by an operation, disease, or just late potty training habits. Youth incontinence products are hard to come by, since youth incontinence is a rarer condition, but there are plenty of people and young adults out there with youth incontinence. It's nice to get a product with a wettness indicator. This would be useful if it is a child and they need some extra help telling that the diaper is full, or for someone with paralysis that can't tell.
