From Tardis Wiki, the free Doctor Who reference
Darren Plant had an uncredited role as the infant John Benton in The Time Monster. (DWM 268)
Darren William Plant was born on 3rd June 1971[source needed]. He died in St Pancras, London, in the September quarter of 1972[source needed]. On the commentary for The Time Monster, John Levene confirmed that Darren had died shortly after his first birthday. This gives him the unfortunate distinction of being the shortest-lived individual to ever have appeared in Doctor Who.
