At 7:30 p.m. you begin your nightly bedtime ritual for your 8-year-old. A relaxing, warm bath. Brush the teeth. You talk about what happened during the day. Read a favorite bedtime story. Sing a lullaby. It ends with a kiss goodnight.At 8:30 p.m. your child quickly drifts off to sleep for a solid 10 hours. Then he or she wakes at 6:30 a.m., bright, perky, happy, and ready for the day ahead.Sounds
