She mentions the child arching his back to indicate that he does not need to use the potty. However, in my experience, Haven arches her back because she would rather do something besides use the potty. For example, just a few minutes ago she woke up from her nap so I took her to the potty. She immediately pooped a little and I praised her. Then she started arching her back. I said, "No, no" and put her back. Then she pooped some more. So when it comes to Haven, arching her back does not mean she doesn't need to potty.
