Our DS started at the State Ballet School in Berlin in January of this, as it as his greatest wish. He was only nine at the time, but adement that he wanted to go and fully aware that he would be away form home, only a two-weekly visit by us possible, as it is about a 5-6 hour drive from where we live (depemding upon traffic, which is generally bad), but he insisted this is what he wants to do. Hence we let him go and the first two weeks were difficult for all of us, his older sister included. The only communication we had was via whatsapp and it never went beyond "yes", no" fine. We agreed every day to call, at a time specified by him and shortly before that time he would send a message asking not to call. However, after the first two weeks were over, all was fine and the messages had more content and we spoke on the phone at least once a day. he has been home for the summer break just now and I was dreading him going back and the same procedure starting again, but all was and is fine. The main thing to consider in all of this are how the children, and surely if we know that they are happy, we are a lot happier too:)
