Disposable Diapers? What disposable diapers? In China the Toddler's split pants 开档裤 kāi dàng kù allows babies and toddlers to answer nature's call with neither hindrance nor hassle. This great Chinese invention allows little kids to do their business anywhere. At first sight it may seem bizarre, perhaps a little embarrassing to foreigners, particularly Westerners to see baby's little Willy or naked butt exposed. I was surprised to have spotted a number of these toddlers in a modern city like Shanghai in this day and age. The Split Pants isn't totally alien to me. I remember when I was young, one of my younger brothers wore them. Not everyone of us wore them. I believe those who were hard to "potty train" were made to wear them. And I remember it's only a small slit at the front for peeing only, not all the way to the back.
