Helping kids Grieve

This past week, we had a change up of events in our household. My dad, who is only 64, went into the hospital and had a few scary days of being extremely sick. It was the first time that our family had to deal with someone close to us being so ill.
As I sat in his hospital room on Saturday afternoon, when he was close to being intubated for breathing, I started thinking about how I would tell my kids if his conditioned deteriorated. We haven't had to deal with such critical issues in our family, as of yet. Therefore, I felt unprepared.
Thankfully he is beginning to turn the corner, although his disease will remain, and he will leave this earth. I want to be prepared to know what to say to my kids. I began researching on the web for books and articles. I found a simple article with some easy steps. Focus on the Family  I hope it is useful to you. Here is a link to some simple books that may be useful. Helping Kids Grieve Books
