'Outnumbered' won't be back for a new series next year.
The BBC One comedy – which stars Hugh Dennis and Claire Skinner as stressed parents trying to control their three children – will now only be brought back for one-off specials as bosses are worried its child stars are too old.
Tyger Drew-Honey, who plays Jake, is 14, while Daniel Roche (Ben) is 12 next year and Romana Marquez, who has won awards for her portrayal of Karen, is about to turn 11.
Tyger said: "There's a special on Christmas Eve. Next year there'll be a 'Comic Relief' special and maybe another Christmas special."
Talking about this year's Christmas special, Tyger said: "My character has a hangover. Grandad's in hospital and we all go and visit him.
"The last Christmas special ended with a bit of a sing-song so there's another one of them."
If the Christmas episode, and the following specials, are a success, bosses may consider bringing the show back in 2013 if they have ideas for the children when they're all teenagers.
Tyger revealed: "The year after that there could be another series.
"I think they don't want to dive in this year and do a whole series because it might not work with the kids getting older."
All four series since its 2007 launch have been ratings hits for BBC One.
