So here's what I recommend (and I have successfully applied): you take an A3 sheet of paper and you'll paste a photo of the child on one side and a visual of the other friendly toilets; both connected by a path you draw. You buy qq boards attractive stickers (I took the animals), and whenever the child is successful experience of the pot, you let him choose a sticker (eg small for a pee and a big for a poo), and paste it on the way. The goal is that once we reached the toilet, the child took assertive enough in the way of cleanliness to be (at least approximately) developed.
Thus you will use your money better and optimize your chances of success!
But really believe me, with regard to this product, go your way ...
