Reddit reviews Lifetimes: The Beautiful Way to Explain Death to Children

I used to be a vet tech and had to help many families explain the passing of their pets to their kids. Believe it or not - kids are more open minded than adults and much more savvy in most cases. Have an open discussion. I would create a scrapbook for him with pictures so he at least feels like he "knows" those people and that they didn't just up and leave for no reason, ya know?

I think when you're both on the same page and have discussed it openly it will help both of you. Try this book because it explains more in depth.
