It doesn't make sense if you view it from the perspective of a happy secure child with a good relationship with parennts.
As part of a therapeutic process I couldn't comment because not ennough is written about it in the mail, and I'm not qualified to judge any form of therapy.
But I have seen children in mainstream schools whose emotional development is so awry that you can see that their ability to learn and to live socially constructive lives as they grow is going to be a big challenge.
If anything can help them , it is worth trying - for all of our sakes!
