In the Pig universe, now running for more two decades, Peppa remains four years old, her brother George two years younger.

The beloved piggy family from TV is expanding! Mama Pig is expecting, and Peppa Pig is about to become a big sister again.

So the arrival of a new sibling will be the first big change to the Pig family in the show's history. Esra Cafer from Hasbro, the company which owns the Peppa Pig franchise, said the new addition will show the "ups and downs" of getting a new brother or sister.
