Well I have tried ds on a potty but he gets his bits stuck, ie, they don't easily fall into place where they should so to speak. He is only just 2 so haven't particularly started potty training in ernest was just introducing things. I have since bought one of those padded seats with handles for them to hold onto that go on the toilet but haven't tried him with it yet.
Was searching the tinternet earlier for alternatives and found this The Weeman, has anyone had any experience of it?
