Learning as a kid would has become a more popular option for people I think, and it makes sense. Learn Korean like a child as the natives learned themselves and you can take advantage of simple media like children’s books, shows, movies, and more to progress with your Korean and strengthen your listening and reading skills!
Many children’s media is easily accessible too, with a lot of Korean kids shows officially uploaded to YouTube for free so you don’t have to hunt down resources or pay for a specific subscription or platform.
