The Canadian strip "For Better or For Worse" had the characters getting older (more noticeably with the children), until the cartoonist decided to reboot (getting rid of the third child, April). Now it's just the two kids and apparently they won't age.

It's Canadian so sometimes the virtue signaling trumps the humor, eh?

I forgot about "For Better or Worse". It started out as a nice, gentle, family strip that was all the more dangerous as it started pushing the "tolerant" social left agenda, because of it's family friendly look and feel, compared to Doonesbury etc.

Funky Winkerbeam also decided to age everyone all at once, after being static for a long time.
