Twinkle, twinkle, little star. How I wonder what you are! Up above the world so high, like a diamond in the sky. Twinkle, twinkle, little star. How I wonder what you are! Parental creatures from around the world lull their babies to sleep in this charming and unique bedtime book. Simply shine the beam of a light (not included) through the ''windows'' on each page to cast its pictures on the wall as you read the rhymes within. It's a fun way to end the day and experience a book together. Please note: For best results, use this shadow book with a small, single-bulb light source. A small pen light, other single-LED light, or the light on the back of a smartphone is recommended. Multi-LED flashlights are not recommended. If you have trouble getting a clear image, try moving your light closer to or farther away from the page. Ages 3 to 9. Sturdy covered wire-o hardcover binding. Bo
