I could probably find a better board for this, but I have come to "know" you folks better.Yesterday my 11yr old daughter came home from school with the news that one of her classmates has been diagnosed with a brain tumour. They still need to do a biopsy so at this point it's not known if the tumour is benign or malignant.My daughter and this boy have been in the same class since Grade 1, they are now in Grade 6. The type of school she goes to, they don't have many kids joining or leaving the class so they are a fairly tight-knit group. This news had my daughter quite upset last night.After school, she spent a few hours online researching brain tumours and asking a lot of questions. Normally, she's not allowed to spend that much time on the computer but it seemed like something she needed to do so I gave her a pass for the evening. She is very interested in medical stories and has already told me which medical school she plans to attend (yes, I know that will probably change) so at this point I don't know if the online research was simply from an interest point of view or if this was her way of coping.Touch wood, I have never had anyone close to me have a serious illness. I don't know how I would handle the situation if I was given that kind of news. I know that some people see gathering as much information as they can as a way of dealing with their emotions. Knowledge is power sort of thing.Myself, I teared up a bit last night when I thought of what this child's parents must be dealing with right now.My question is: in preparation for this evening, assuming she jumps back online (which she may not, I don't know) how far do I let her run with this and when is it time to put my foot down?
