I agree with others that a phone call would be good. I know what you mean about the website box, but we are all olds

I would not give up on a great program simply for that reason. I get what you mean about not wanting her to be a pain. That’s important. But if there’s an overall feeling that they don’t care about her concerns, that’s important.
I was just thinking about how there are a few schools that have really seemed to care about my questions and give me a warm welcome, even if they had no good answers for me. I’m more inclined to feel like my kid would be listened to at those schools.
