It think if she is as you describe her you might want to somehow delicately inform her to your and her rights as she might do something while you are not around and unintentionally hurt a child.
She was actually uncharacteristically cooperative when I told her the danger and that this needed to stop now. So that part won't be a problem. I am just worried about how much damage she did. I can't believe she would use her prescription creme (that her own doctor warned her to use only twice a day) so blithely on a baby. "It worked for me!".
