Tony Tyler

Tony Tyler was the young child of Jackie Tyler and Pete Tyler. In the time between Battle of Canary Wharf and the first journey to Bad Wolf Bay, Jackie had fallen pregnant. (DW: Doomsday) Two years later, Jackie jokingly stated that she had named her son 'Doctor' to tease The New Doctor, before revealing that the child's name was Tony. (DW: Journey's End)

While Jackie was fighting the Daleks, she left Pete on the "nursery run" to look after Tony.
