Do kids do this in other languages, too?

Listening to my niece playing with a friend and it reminded me of something strange - Norwegian kids, when playing, switch dialects. It's like this over all of Norway - when kids play, their dialect changes into a southeastern Norwegian one. As our dialect is a North-western one, the difference is really damn stark.

It's so normal here I rarely think about how weird that is. Is this universal? 🤔
