Our son wanted to, not on the Topf.Was me sometime nervous as he made to go to the 3 and eigentich should be dry times. Eventually, I did not ask him why and he said to me: it hurts .. ?? out I let him sit on it and found that the Opening on a normal pot was too small and he had to squeeze in the important parts. We sought out a pot of boys is suitable and we opted for the Bobby car ... It was delivered promptly and sat out of the box and sample !!!!!!'re where we need during the day no more diaper ...... More probably there to say.
