Never miss an opportunity to allow a child to do something she can and wants to on her own. Sometimes we're in too much of a rush--and she might spill something, or do it wrong. But whenever possible she needs to learn, error by error, lesson by lesson, to do better. And the more she is able to learn by herself the more she gets the message that she's a kid who can.
