Shrinking Potties ???

I know, it sounds strange but I truly have to believe that all the potties in the world are shrinking! At first I thought our new home just had smaller potties but now I know that it must be all potties that are suddenly smaller.....by now you are surely wondering why I am worried about potties, right? Well, my "little" boy no longer needs a stool to pee pee in the potty! It just can't be possible. He isn't even three yet. I guess the old saying is true...They just grow up too fast. I will still claim all potties are shrinking, atleast for a little longer.
