We had some toilet trainer in use ... also in which yellow / red / blue design with feet, which are also just launched, unfortunately all did not work alone ... unstable and wobbly. Not this one, the small step can also be removed when the child grows and the intermediate no longer needed. It is safe and the child may well own up and down, even without parents present in the bathroom. When setting up to the bathroom, we have to help, though. My star minus, the colors remind me totally at hospital or nursing home, because I was shocked. I'm sorry, but that should be changed. An appealing color concept is for me also to functional design. Is also only a suggestion to the manufacturer, if the read here) As a mother, I am satisfied!
