Lenny's book of everything by Karen Foxlee

Lenny's book of everything by Karen Foxlee. Allen & Unwin 2018. 

I have read a lot of children's books on death, this is the only one I can think of that ends so soon after the death. Instead, it focuses on relationships and the growth of preparatory grief.

It is perfectly paced and nuanced. Each character plays their roles, and there is little stereotyping.
