Aside from entertainment, a parent’s biggest stressor when taking a road trip, even only a couple hours away, is a child’s need to potty at the most impossible times. This purchase was one of my most outrageous purchases, but I have used it hundreds of times. The ONEDONE Portable Child Potty is so great for going potty on the road. It is compact, discrete, and the design prevents the urine from escaping out of the cup if the cup gets knocked around. They have a boy and girl version, and it is impressive how well they work!
