You might check to see if your child's identity has been stolen. That's happening alot these days. These types of scammers usually pray on people who may have had credit problems in the past, so if they are calling for her, it might mean someone is out there using her social security number.
Not trying to tell you what to do, but I'd just check into it if I were you.
You can call any of the major credit reporting firms to find out of they have activity under  your child's social security number.
