Thank you so much, I'm definitely going to look at those books. Especially the one about how to talk about death with children because I'm pretty sure I'm failing at it.
Ollie asked where Poppop went and I completely forgot all the responses I had worked out and basically rambled until I finally told him Poppop had gone to heaven and now he's one of the stars watching over us and that although we can't see him, he still loves us very much. Which prompted my child to look up at the sky and yell "Love you too, Poppop! Get down! Come back down, Poppop!"
