I hear a lot of people say, “Kids pick up languages so much faster than adults.” Now that I have a small child, I think one of the reasons why is because of their tendency toward repetition.
How fast would anyone learn a language if they were repeating the new words over and over and listening to the same thing a hundred times? Little kids can watch the same video 317 times and still want to watch it again. [FYI, this works really well for kids’ Youtube channels!] You can read them the same book every day for a month and they will still want you to read it again. I have to sing the same song over and over and over.
