My youngest loved this book! He particularly liked reading a science book, meant for his age (preschool), just like his bigger brothers read science books. It has a nice story line if you just want something sweet and rhythmic for bedtime, and then the last page is filled with facts if you want to go deeper (not at bedtime!). It was interesting to learn, for example, that astronauts use velcro to hold their forks down between bites, and that their visors on their helmets are lined with gold.
