I opted not to read this one to the kids because half of the book is about a big scary storm. We get one or two thunderstorms a year so normalizing a storm isn't a concern for me. I just know that my little one (3.5) has recently been more spooked by things. I am very thankful for another review that pointed out the storm because I had assumed that a goodnight book would be more calm in nature and had intended to introduce this to us both at bedtime, which wouldn't have worked out well.
