Mummy Pig is pregnant. That’s right – Peppa Pig’s mum is having a baby, and the long-running animated series will be forever changed. In an episode that will premiere – appropriately – on Mother’s Day on 30 March, Mummy and Daddy Pig will break the news to their children that a new baby is on the way, with the show’s forthcoming 11th season exploring, over time, the pregnancy and birth.
