I'm in the process of trying to PT my almost 3 year old. One big issue were having is it takes her forever to sit even if she is trying to make it. We have a stool but she has to position it just so and its always in the wrong place then honestly it almsot doesn't seem to be enough support. I'm wondering if something liek the above would be better?? IF not then I might need a seperate potty but I REALLY dont want to go that route simpily from a small space POV.
