I second @Publisher’s comment. If we had had a truly strong LPS option that our son was happy with, boarding school never would have been an option. However, we knew he was “ready” when he asked if we would be open to considering BS for high school. He had been poking around on the Internet for better high school options and had come across boardingschoolreview.com which led him to school websites. What he saw excited him. We went from there. Eventually, we told him if he could get in he could go. He never looked back.
We know what you mean, but none of us sent our kids away; we allowed them to go. It’s an important distinction on this board, but hard on us no matter how you phrase it.
