Sleep is more than rest — it helps kids grow, learn, and feel their best. With busy schedules, screen time, and school stress, children often don’t get as much sleep as they need.

Understanding child development and sleep and pediatric sleep guidelines can help families build healthy routines and catch sleep problems early.

What Are Sleep Recommendations by Age?

Children need different amounts of sleep as they grow. Young kids need more sleep to help their brains and bodies develop.

However, older kids and teens still need plenty of sleep. They often get less than they need because of changing schedules and late nights.

Recommendations for sleep by age:

• Newborns (0 to 3 months) — 14 to 17 hours.
• Infants (4 to 12 months) — 12 to 16 hours.
• Toddlers (1 to 2 years) — 11 to 14 hours.
• Preschoolers (3 to 5 years) — 10 to 13 hours.
• School-aged children (6 to 12 years) — Nine to 12 hours.
• Teenagers (13 to 18 years) — Eight to 10 hours.

Why Is Sleep Important for Child Development?

Sleep plays a big role in how kids grow and function every day. While sleeping, their brains are busy organizing thoughts, building memories, and clearing out extra information. Their bodies fix tissues and build strength for the next day.

It also allows their body to fight off sickness and control emotions. During deep sleep, kids release growth hormones and store new information in their brains.

What are signs of sleep deprivation in children?

Kids who don’t sleep enough may not always seem tired. Some may become more active, not less.

Signs of sleep deprivation in children include:

• Cranky moods or frequent meltdowns.
• Extra energy or wild behavior.
• Falling asleep in the car or during quiet time.
• Hard time waking up in the morning.
• More headaches or clumsiness than usual.
• Trouble focusing or finishing schoolwork.

Adopt healthy sleep habits or better bedtime routines if you notice these signs. Missing sleep could have a long-term impact on health.

What Are Healthy Sleep Habits for Kids?

Healthy sleep habits support good sleep hygiene (the practices and habits that promote good quality sleep) and can make bedtime routines more efficient.

How can I create a healthy bedtime routine for my child?

Infants and toddlers

• Avoid rocking or feeding babies to sleep, which can become a habit.
• Keep the same bedtime and wake-up time every day.
• Keep the room dark and quiet, with a white noise machine if needed.
• Put your baby down drowsy but awake, so they learn to fall asleep on their own.
• Use a simple routine including bath, book, lullaby, and sleep.

Preschoolers and younger kids

• Avoid sugary snacks or exciting games close to bedtime.
• Make a bedtime chart with simple steps they can follow.
• Offer praise when your child sticks to the routine.
• Turn off screens 30 to 60 minutes before bed.
• Use nightlights or comfort objects to ease fears.

School-aged kids

• Encourage active play during the day to help burn off energy.
• Keep bedrooms quiet, dark, and relaxing.
• Set clear screen time limits and keep screens out of the bedroom.
• Stick to the same bedtime, even on weekends.

Teenagers

• Encourage a bedtime routine that helps them wind down and prepare for sleep.
• Help them set limits around phone use and late-night studying.
• Talk about why sleep matters and set a good example with your habits.
• Understand that teens naturally want to stay up later but still need eight to 10 hours of sleep.

How do naps affect total sleep for toddlers and babies?

Naps are an essential part of sleep for babies and toddlers. Unlike older children and adults, young children aren’t able to get all the rest they need in just one stretch of overnight sleep. Their developing brains and bodies require more frequent rest periods to recharge and grow properly.

During naps, babies and toddlers go through the same important sleep cycles that happen at night — including deep sleep and REM (rapid eye movement) sleep. These stages help with memory formation, learning, physical growth, and emotional development.

Naps also help regulate a baby or toddler’s internal clock (called the circadian rhythm), which sets the foundation for healthy sleep habits later in life. When timed well, naps are part of a consistent routine and they improve mood, attention span, and overall well-being.

As children grow, naps become less necessary — but they can sometimes still be helpful.

• Infants (4 to 12 months) require two to four naps per day.
• Toddlers (1 to 2 years) need one to two naps per day, finishing before late afternoon.
• Preschoolers (3 to 5 years) need one short nap or a period of quiet time.
• School-aged kids (6+) usually don’t need daily naps.

Should older children nap?

Most older kids and teens don’t need naps if they sleep well at night. But short naps (20 to 30 minutes) can help if they didn’t sleep enough the night before or need a quick boost. Long or late-day naps, however, can make it harder to fall asleep at bedtime.

You might notice your child benefits from a short rest during the day if they:

• Are going through a growth spurt or a tough school week.
• Fall asleep easily at bedtime.
• Had a poor night of sleep or felt under the weather.
• Wake up feeling refreshed after a nap.

On the other hand, naps may interfere with healthy sleep habits if your child:

• Has trouble sticking to bedtime routines.
• Needs a nap every day, even after a full night’s sleep.
• Takes long or late naps and then struggles to sleep at night.
• Wakes up groggy or confused.

If your child is over age 6 and often naps but still seems tired, it might be time to check in with your pediatrician.

When Should I Call My Child’s Doctor About Their Sleep Problems?

Kids do have the occasional bad night’s sleep. But if sleep issues happen regularly or affect your child’s health, mood, or school life, it is time to seek help.

Here are a few examples of when to see a doctor for a child’s sleep problems:

• Regular nightmares, bedwetting, or sleepwalking.
• Sleeping nine to 10 hours, but still feeling tired every day.
• Sleep problems affecting their behavior or learning.
• Snoring loudly, gasping, or stopping breathing at night.

Keep a sleep log, noting bedtimes, wake times, and naps, and share it with your child’s doctor.
