Alison Lester's 'Monsters are Knocking' is a reassuring picture book that gently tackles common childhood fears of the unknown. The story centers on children who perceive shadowy figures at their door as scary 'knockers.' The narrative builds a mild suspense before the children bravely decide to open the door, revealing that the perceived monsters are, in fact, harmless and familiar objects or people. This book is ideal for young children, particularly those aged 4-7, who are grappling with nighttime anxieties or fears of imaginary creatures. It normalizes the feeling of fear while modeling a positive way to confront it, offering comfort and a sense of empowerment. Parents can use this book as a springboard for discussions about shadows, imagination, and how things might not be as scary as they first appear. Its simple, repetitive structure makes it a great read-aloud choice, perfect for a calming bedtime story.
