According to Eyberg (1988), the Do rules of CDI that promote positive behavior throughout play. The first Do is to describe what the child is doing during the activity. Doing this may seem unnatural at first, but describing serves a few purposes: it allows the child to (1) lead play, (2) improve attention towards independent activities, (3) clarify the activity and encourage the child to further elaborate the play, and (4) help teach the child different concepts in a positive way. For example, the child learns through positive feedback (“you found the red one”) instead of coercion (“find the red one”).
