Those Tranquility diapers are EXCELLENT!!! I havne't used them on my daughers, because they can fit into Pull-Ups easily, but I used them myself for quite a while before I switched medical insurance due to a neurogenic bladder and bowels.
They are a bit thicker than other adult-type diapers, but they have some features that are unique to that brand:
They actually reduce rashes by reducing the urine ph level after your child pees in the diaper.
They have a nice wetness indicator that allows you to use the diaper longer than most others (you don't change until the wetness indicator is 3/4 of the way a different color: they call this a Komfort Monitor).
They have leak guards, so nothing escapes the diaper, even if they pee quite a bit. Their peach core also keeps wetness completely away from your skin.
They have dual refastenable tape tabs, so you don't tear the diaper trying to readjust it.
They don't have a elastic waistband, so air can circulate to the person's bottom.
This company also makes youth sized diapers for kids who are too big for adult sizes, but too small for baby/toddler sizes. They also make a diapers just for nighttime called ATN Briefs.
Another diaper company you might look into is TENA. They have youth sized diapers that have similar features as the Tranquility ones, but the outer cover is cloth-like instead of plastic.
If you go to Tranquility's website (I'll look up the site and post it here for you), they can send you free samples to try out. Also, www.hdis.com
has sample packs of youth diapers you can try out and sells the diapers by the case.
