This beautifully designed infant potty fits babies from newborn to 2, I reckon, depending on the 2-year-old bottom in question. My older son used it (some) since birth—regularly since three months. It’s affordable and comes in pretty colors, which must be why we had one in every bathroom, one at the farm, one at my office, and in the car. On the road, I carried it in a cotton net bag—the kind you use at farmers’ markets—so it air-dried. babybjorn.com/bathroom/potty-chair
