I just wanted to add that as a mandated reporter, as said before, it isn't m y job to investigate, just call CPS if I suspect abuse. The info you have given wouldn't make me call, so I wonder if your dd said something else. But, just to reassure you, most of the time when I have called CPS, I say, "Uh, I have a concern, but I don't know if it is reportable," and they have said "Thanks for the call, but that is not reportable." They did not take a report. So, just because there is a call placed does not mean anything will happen.
I hope you and your dd are doing well.
