A. The term Diaper Service Quality (DSQ) is used to describe a high-absorbency, long-enduring, pre-fold cloth diaper. DSQ comes from the days when parents who could afford to had high-caliber, clean cloth diapers delivered to them each morning (and the dirty ones taken away). Today, of course, parents who prefer cloth diapers usually buy and wash their own, and with all of the different pre-folds available through myriad online retailers, they need to be able to gauge which will keep their baby driest and last through many washing machine cycles. If you're in the market, keep your eye out for the DSQ descriptor, but take a look at the thickness of the diaper as well. It should be indicated by a measurement such as 4x8x4, which indicates the number of fabric layers within the diaper: four on the edges and, in this case, eight in the middle, where it needs to absorb the most moisture.
