Not really what I was expecting but an interesting book, from a new collection. The collection present «unpleasant» emotion with character experiencing them in normal casual life stuff and showing them, it also tell us that it's normal to fell like that and help the children to learn how to overcome those feelings. This one is about worry, as the title says. My only complain with it, and what didn't allow it the five stars approval rating was the too obvious teaching lesson in it. I would have prefer it to be more «disguise» into a story with a moral in it instead of being plain obvious life teaching lesson book. Still worth it and can totally be useful for children and parent!
