I've read some pretty horrific things lately about boarding schools and the damage they can cause. See this article from the Guardian.

However, I have no personal experience of one and have no close friends who went to one. Therefore, I don't want to be hasty in forming a negative opinion about them.
So, if you chose to send your child to a boarding school then I'm curious as to why you chose to? For example, why did you chose boarding over a really good day school? Is there anyone who chose a boarding school for a much younger child and was this a really hard thing to do?
