My thoughts are with both you and your Mom at this time. In regards to your nephew, every child is so unique and in their stage of maturity. But, at eight years old, I personally wouldn't volunteer a lot of information. I would be very brief and not go into any detail regarding the process. Rather, keep it simple, loving and caring regarding where Tony has gone and not so much emphasis on the means in which he will return to the earth. And, if he continues to ask further questions, I would choose the words I use carefully and again, be as brief as possible.
I just noticed the date on your post, so I guess this is all very late. I'm so sorry.
Please give your precious Mom a big hug from me. And, a big hug coming for you, too!!
My Love,
Terry
