#diagnosis

Do I share my child's diagnosis with them or is it better to not tell them?

As my son goes through several tests (ADHD, Ados, and who knows what’s next) he’s asking why? As of now, the only thing I’ve said to him is “we’re doing this to see if we can help you feel more comfortable and see if maybe you can get that help in therapy…” Is that the direction I should take?
If he is diagnosed with XYZ, should I not mention it to him?
