My 3 year old and I both enjoy finding familiar details such as the the tandem bikers, the beach ball left at the pond overnight, the family's red truck as the day carries on in the book. There are no protagonists here just people doing what they do.
I also appreciate how the text is written into the illustrations. The words fill a cloud or bump along the top of the garden. Their appearance even illustrates the meaning of words: the word "up" is raised and the word "down" is lowered. The font is similarly suitable, straightforward and legible yet whimsical in the way it is sometimes level and other times free flowing.
