Grace has had a couple of accidents at her friend's house lately. She gets too busy playing, I suppose. So when she told me (in time), "I feel I need to go to the bathroom..." I helped her onto that porcelain seat and sang her praise.
"Grace, you are such a big girl! I'm so proud of you. You did a great job making it to the bathroom in time. You are great."
Her polite response: "Thanks Mom. You're a great wiper."
