Doing things over and over again might help children learn new things.
“Again!” My 4-year-old son Edwin likes to yell over and over again when he finds a new activity or joke that he likes. My 16-month-old, Charlie, likes to repeatedly throw objects on the floor from his high chair or even against the wall if it makes an interesting sound. They both like to hear the same stories every night before bed, they like to eat the same foods for lunch, they like to play with the same toys and watch the same movies every day. When they find something they like, they want to do it over and over and over again.
Why do children like repetition so much?
