Thank for the clarification.
Unfortunately it seems you were taken advantage of. Since it was done through the courts, that means you need to return to court on a motion to terminate the guardianship
since there are no longer any issues that require her further taking care of your child(ren). Had this been only a power of attorney, then you could have easily revoked it by giving her a written revocation notice, but since this was done through the courts, you need to have the court terminate the guardianship. I don't see why it cannot be terminated, only that you have to go to court to get this done. In the mean time she does not have to hand the child over until the court terminates the guardianship.
