Peppa is 4 and George is 18 months (until the episode where he has his 2nd birthday).
Due to getting older, Peppa's voice changes throughout seasons of the show.
Some of Miss Rabbit's jobs include: supermarket cashier, ice cream seller, museum cashier, school bus driver, train driver, recycling depot manager, ice rink manager, hot air balloon pilot, librarian, rescue helicopter pilot, volunteer firefighter, and Christmas tree seller. Miss Rabbit has a sister, also named Mummy Rabbit, and it is possible they share these jobs.
Although the show only features anthropomorphic animals, Santa Claus, a pirate and Queen Elizabeth II are the only three human characters to appear in the episodes.
Some controversy surfaced over the first several seasons of the show. When Peppa and her family are in their car, nobody was wearing seatbelts. The producers considered the criticism so important that they reportedly ordered replacement animation for those shots. When those early episodes are now shown, Peppa and her family are shown properly bucked up.
