Are the kids' counselors allowed to share things with the parents?
If they have the kids permission. My D in counceling is almost 18 and she's been going for a few years. I get invited in for updates every now and then. The deal breakers are if they threaten to hurt themselves of someone else.
Of course the kids can share if they choose to and my D's C encourages her to tell me things that are important. After we found a good match for D17 it's been a life saver. I should probably add though that my D was in crisis (cutting, suicidal).
