I would read this book in my infancy but I can no longer find it. It is about a blue bear (if I remember correctly) who's owner is very sick and he dreams of one day being in the moon with his owner. One day the bear falls out of the window and is forgotten, he deteriorates away with weather and insects that crawl and eat him away. Until one day he is found and his owner had passed away. I can't remember anything after that only that the very last page he finally found his owner in the moon. It's a beautiful story and It made me cry every time I read it haha.

Can you define "infancy" for me?

Furthermore, do you think that it was a children's book?
