Baby On Board (Nappy Version)

Sometimes, the biggest of journeys begin in the smallest and most unexpected places.
Danny and his new wife were taking an interstate bus trip and before they were married, he admitted to his strong desire to be a baby again to which Sue, surprisingly replied that she was okay with it but that they would act on it once they had finished their honeymoon. Sue desperately wanted children but was unable to have them and Danny... he fit a hole in her life in this regard.
But the journey back to infancy didn't wait until they returned home. A man began the bus trip but a nappied baby was there at the end.
