I could go the "do not bring it up" route until we get an appointment with his former therapist. I would not say that he has recurrent fears of hospitalization himself, but he has asked me about it a few times. What it is, why someone would need to go, if I think he would ever need to go, etc. I think it was spurred on by a kid at school joked who with him that he needs to "go to a mental hospital" when he was being overly active. Kids, huh?
Psychiatric hospitalizations are usually a few days, not a few weeks. He will likely be home to play with next weekend.
I think you need to think about the other kid's privacy. If your kid is likely to talk or ask questions at school, then I wouldn't tell.
