While there might be, there is none that we know of! We know that by default many parents have relied on the “hover” method–holding their child up by the armpits while using a public toilet or any toilet that is standard-sized. The products we have offered utilize the standard-sized toilet itself, as is! We do this through a method of accommodation, almost like a booster seat is used in a restaurant. Check out those products for the most convenience. In the meantime, if you find out about any potty training harness equipment, let us know!
