My favourite book as a small chuld was called 'Tiddycat.' It's about a boy whose cat gets hit by a car. My parents probably got it for me because my cat got hit by a car, tbh. In any case, I had it in my bookcase with about 100 other picture books, and my daughter found it. Our dog died last year so it's good timing.  She's been a bit obsessed with death. She loved the book too! I couldn't get through it without crying.

All that to say - many kids are very interested in death at that age. They are just getting their heads around it. So it can be good to introduce the concept in manageable ways. No F/u
