You have heard of a bicycle built for two, right? But a potty? It is the new invention of the trio's (well, actually, just Gabby & Mateo).... It works by Gabby sitting on the potty and peeing while Mateo stands along side of the toilet- peeing behind her.
Gasp?!? You say? So did I... and they looked at me and said, "see Mom, there's plenty of room for both of us to go!"
