Why does self-esteem generally increase during childhood?

When children feel good about themselves, it sets them up for success — in everything from school to friendships. Positive feelings like self-acceptance or self-confidence help kids try new challenges, cope with mistakes, and try again. Taking pride in their abilities and accomplishments helps kids do their best. 

By contrast, kids with low self-esteem might feel unsure of themselves. If they think others won't accept them, they may not participate as often. They may allow themselves to be treated poorly and have a hard time standing up for themselves. Kids who don't expect to do well may avoid challenges, give up easily, or be unable to bounce back from mistakes.
