Let’s Do It Again ... and Again ... and Again ...
Through repetition, toddlers figure out how things fit together and work. They might fill and dump a pail over and over to learn about full and empty and in and out. They may want you to read the same book, and sing the same song, night after night. This kind of repetition helps children know what to expect. This gives them a sense of security and control over their world. It also helps them master new skills,
which boosts their self-confidence.
