In the US, an amateur radio operator can be the control operator for an unlicensed person. Usually, the control operator is at the control point, but I’ve had roaming unlicensed Scouts with HT where an adult was the control operator.
If you were control operator, you would be confident that she could operate the radio within your expectations, using your call sign.
Not sure how you log the same call sign on both ends of a QSO, but that is a problem for the database.
