So we are in very early days of potty training. Our ds (21m) adores the potty, and he is asking to use it. Happy to sit on it, stand by it, but also really keen to take it for walks, use it as a hat. Should we allow or should we restrict usage to specifics? When we take him off it and restrict it he has a mini meltdown. Should we allow him to take possession of it or set boundaries?
