Yes, I also used to discuss news with my daughter, such as the news of students committing suicide, but have not mentioned this teacher's news to her, as I don't know how to answer her many "Why" for this case!!
Yes, I did. In fact, they are interested to know the reason behind. I've just made some assumptions and have analyzed how the situation can be solved if problem of this may arise. They are capable to think and make statements now and they reacted quite normal.
I will not disclose it or conceal it deliberately. If they know and ask, I will answer it and implant the +ve thinking to them. I would not discuss it in a proactive manner as I am afraid that they are too young to analyze what I want to share. But I would keep on giving them +ve thinking ... : :
