Child Sleep Requirements Calculator
Calculate the recommended daily sleep hours for your child based on their age, following American Academy of Pediatrics (AAP) and National Sleep Foundation (NSF) guidelines.
Child's Age (Years)
Child's Age (Months, if under 1 year)
Current Bedtime (optional)
Current Wake Time (optional)

#### Formula & Classification
Sleep requirements are determined by mapping the child's age to evidence-based ranges:
- Newborn (0–3 months): 14–17 hours/day
- Infant (4–11 months): 12–16 hours/day
- Toddler (1–2 years): 11–14 hours/day
- Preschool (3–5 years): 10–13 hours/day
- School-Age (6–12 years): 9–12 hours/day
- Teenager (13–17 years): 8–10 hours/day
Optimal Target = (Min + Max) / 2
Actual Sleep = Wake Time − Bedtime (adjusted for midnight crossover)
Suggested Bedtime = Wake Time − Optimal Target Sleep Duration
Sleep Deficit = Min Recommended − Actual Sleep (if negative)

- Recommendations follow the American Academy of Pediatrics (AAP) 2016 guidelines and National Sleep Foundation (NSF) 2015 consensus.
