Parenting Coordinator?

[Foster_Mom]

Has any one ever had a Parenting Coordinator assigned to thier case and what is it? Any comments on this subject are appreciated. Our BM is throughing a tantrum becuse she is not getting her way with the kids changing schols and she is petitioning the court to assign a parenting coordinator. We have never heard of this but are concerned as to what the point of this type of profesional is for and what we should do about the situation.
