When my son was 5, he was still really in his shell. His Dad and I took him to the park after buying him some softball gear, and we were trying to help him learn to swing at the ball and hit it. He wasn't hitting it too much, and I just adore him so much, so I was worried that he would get too discouraged or even upset. Somehow he sensed my anguish for his comfort, and said quietly, "It's okay, Mom."
He was comforting me! What a wise little son.
