About This Calculator
What It Does
This calculator provides age-based sleep duration guidelines and suggests bedtimes or wake times based on the child's age and your schedule preferences.
Worked Example
For a 6-year-old child, the recommended sleep range is 9-12 hours. If you want them to wake at 7 AM, the calculator shows appropriate bedtimes based on 90-minute sleep cycles within that range.
Real-World Usage
Children's sleep needs change as they grow. Infants need the most sleep but wake frequently. Teens often experience a natural shift toward later bedtimes. Nap needs decrease as children get older.
Local Context
Sleep recommendations are based on guidelines from the American Academy of Sleep Medicine (AASM) and the CDC. Individual sleep needs vary β use these as a starting point and adjust based on your child's behavior and well-being.
