If you’re looking for something feel-good, look for Debi Gliori. Two of my favourite books as a slightly older child were Tell Me Something Happy Before I Go To Sleep (Written by Joyce Dunbar, Gliori is the illustrator) and No Matter What (written and illustrated by Gliori).
I must have had a thing for rabbits, because Tell Me Something Happy features a brother/sister duo of rabbits named Willa and Willoughby. Willa can’t fall asleep, so she asks Willoughby to give her happy things to think about while she falls asleep.
Willoughby is remarkably patient for an older sibling who is being prevented from sleeping; I know I was never that nice when my younger siblings talked at night. He keeps asking Willa what she sees in their surroundings and then tells her a story about the items she sees. For example, her chicken slippers (she’s a bunny, so bunny slippers would be weird right?) are under the bed waiting for her to wake up so that she can hop out of bed and put them on. After enough happy thoughts, Willa is able to fall asleep and leave Willoughby in peace. I’m sure my parents related to this book fairly closely. I was never the kid to fall asleep quickly, and so there were many nights where I was Willa, while my dad was patient Willoughby.
No Matter What is about as close to perfect as you can get if you’re trying to show your unconditional love for someone small. The book follows a conversation between two foxes, Large (the parent) and Small (the kid). Small states that they are “grim and grumpy” because they think Large doesn’t love them.
The book continues with Small asking if Large would still love them if various things happened and Large patiently reassuring Small that they will be loved “no matter what”, even if they were a squishy bug or a crocodile. Large reassures Small that love does not break or end and that it reaches far away, just like the light from the stars.
Both books are so easy to read because of their relaxed rhythm and, in the case of No Matter What, rhyme scheme. The phrases fit together naturally, drawing the story forward without any feeling of forcedness. Neither book is as poetic as Goodnight Moon, but the style serves the purpose of the stories quite well. Both books are reassuring and intimate, both in story and style. I think that’s part of why I appreciate them to the extent I do.
