This book has just the right amount of puns, including the title. The author and illustrator didn’t take it too far and make it farcical.  Donut has lots of worries and everyone telling her it will be okay isn’t helping.  Until she meets a crumbling cookie who tells her “It’s okay to not be okay”.  I think this is a lesson we need to teach children more.  So many people want happy healthy children, or make light of a child's worries and fears, it’s nice to have something, or someone says, It’s okay to not be okay.  This book works in all ways.  The illustrations are great with the puns and the topics.  It’s approachable without seeming like a lecture, and a fun to read book that isn’t just about it’s lesson.
