I'm sure it's not illegal for your dtr to take a neutral support person with her...I'm very sure they can't stop that....start looking for someone your dtr wants in there with her...if she demands it, they have no choice but to allow it or your dtr can refuse to go in there.

It's basic rights of every human especially that of children...the same for you, have a support person with you...it's allowed!

Demand it, your dtr can demand it and do so...
