- Sleep needs change significantly as children grow from infancy through adolescence.
- Total sleep includes nighttime sleep and daytime naps for younger children.
- Every child is different โ use guidelines as a starting point, not a rigid target.
Newborns (0-3 months)
Newborns need 14-17 hours of sleep per day, but it is distributed across multiple sleep periods. They wake frequently for feeding and do not have a consolidated nighttime sleep pattern until around 3-4 months.
At this age, sleep is unpredictable and varies significantly between babies. Focus on safe sleep practices: back to sleep, firm mattress, no loose bedding, and a cool room temperature.
Infants (4-11 months)
Infants need 12-16 hours of sleep per day, including naps. Most infants take 2-3 naps per day by this stage. Nighttime sleep consolidates to 9-12 hours.
Around 6 months, many babies are capable of sleeping through the night, though individual variation is normal. Consistent bedtime routines help signal that it is time to sleep.
Toddlers (1-2 years)
Toddlers need 11-14 hours of sleep, including 1-2 naps. Most toddlers transition to one nap per day around 15-18 months.
Toddler sleep challenges are common: separation anxiety, night waking, and resistance to bedtime are normal developmental stages. Consistent routines and comforting sleep environments help.
Preschoolers (3-5 years)
Preschoolers need 10-13 hours of sleep. Most children in this age group stop napping by age 4-5. Nighttime sleep consolidates to a single block.
Bedtime resistance and night fears are common at this age. Limit screens before bed, maintain consistent bedtime routines, and ensure the sleep environment is comfortable and dark.
School-age children (6-12 years)
School-age children need 9-12 hours of sleep. Busy schedules with school, activities, and homework can make it hard to get enough sleep. Sleep debt accumulates quickly in this age group.
Signs of insufficient sleep in children include irritability, difficulty concentrating, hyperactivity (sometimes mistaken for ADHD), and falling asleep during the day.
Teens (13-17 years)
Teens need 8-10 hours of sleep, but many get less. A biological shift in circadian rhythm during adolescence makes it hard for teens to fall asleep early, while early school start times force early waking.
This combination leads to chronic sleep deprivation in many teens. Later school start times are associated with improved academic performance, mental health, and safety outcomes.
