American parents say their children have started speaking with British accents because of "Peppa Pig."

Parents have taken to social media to share stories of their toddlers developing British accents.

The phenomenon has been dubbed the "Peppa effect."

American parents say their children have started speaking with British accents because of cartoon Peppa Pig.

The children's TV show, which follows Peppa's life in a fictional UK town as she spends time with her family and animal friends, has achieved global success in recent years.

And in the US, young viewers appear to be adopting her southern British accent and vocabulary after watching the show.

Dozens of parents have taken to Twitter over the phenomenon, which has been dubbed the "Peppa effect."

Dad Sylvester Kabajani said: "My four year baby girl loves watching Peppa Pig and I have noticed her accent and grammar is extraordinary.

"Last night I tucked her to sleep and she looks at me and says 'daddy, can you snuggle me' I was like what did you just say baby girl? I don't remember the last time I used that word."

Film critic Clayton David wrote of his son: "Best thing that Noah does these days is speak in a British accent b/c of Peppa Pig.

"2 days ago, he came to me & said 'Daddy, I want to sit on your lap and use the computer'."

"I'd like to thank Peppa Pig for the slight yet adorable British accent my toddler is acquiring," added mum Jen Rofé.

Mike Lupa said: "Anyone else's kid developing a slight British accent after watching Peppa Pig?"

"She's also snorting like a piggy, but that is expected."

Jess Steinbrenner added: "The most entertaining aspect of my life right now is that my toddler has been watching Peppa Pig and now speaks with a British accent."

US mother and writer Janet Manley dubbed it the "Peppa effect" in a recent article for Romper, saying her daughter had started "calling me ‘Mummy' and finishing her sentences with Peppa's trademark snort".

"Two years later, she still oinks in conversation. Call it the Peppa effect," she said.
