I'm sorry to hear about your son's CDH. My wife is an experienced nurse, and I always make an effort to learn about various diseases and how to stay healthy or regain health:

What a scary condition. You must be under terrible stress!

We have since then acquired alot of skills as nurses taught us before we could be discharged. Thank God my son survived. Living under terrible stress, no doubt, but thankful enough that he is still with us. He just weaned off from his bi-PAP and now is learning to eat.
By the way, I can't stand gossip too.
