Children's Sleep: A Guide to Sleep Hours by Age

Posted by Leafsleep on September 11, 2026

Getting the right amount of sleep is essential for children’s growth, learning, and well-being, but sleep needs change rapidly as children grow, and a good night’s rest also depends on a comfortable environment tailored to each stage of development. At Leafsleep, you’ll find crib and children’s mattresses designed to support little ones from their earliest years.

Sleep is not measured the same way in all stages

Sleep needs change as a child grows. In the first few months, sleep is spread out over several periods throughout the day; later on, sleep gradually becomes concentrated during the night and keeps pace with new physical, cognitive, and emotional demands.

Therefore, when discussing children's sleep, it is important to consider not only their age but also the way each child wakes up, plays, learns, and recovers. The recommended hours serve as a useful guideline, not as a rigid, one-size-fits-all goal.

Hours of Sleep by Age: How Much Sleep Should a Child Get?

As children grow, the recommended amount of sleep gradually decreases. The guidelines below take into account total sleep over a 24-hour period, including naps at ages when they are still part of the routine.

From 4 to 12 months: 12 to 16 hours

Between 4 and 12 months, babies generally sleep between 12 and 16 hours a day, including naps. At this stage, sleep is still spread out over several periods and gradually becomes more concentrated during the night.

Ages 1 to 2: 11 to 14 hours

As the child grows, the total number of hours begins to decrease. Between the ages of 1 and 2, the recommended amount is 11 to 14 hours in a 24-hour period, with room for one or more naps, depending on the child’s routine and individual needs.

Ages 3 to 5: 10 to 13 hours

During the preschool years, between the ages of 3 and 5, 10 to 13 hours of sleep per day are recommended. Some children continue to benefit from an afternoon nap, while others gradually transition to getting all their rest at night.

Ages 6 to 12: 9 to 12 hours

Once children start school, their schedules become more demanding, and sleep begins to compete with activities, homework, and leisure time. For children ages 6 to 12, the recommended amount of sleep is between 9 and 12 hours per night.

Ages 13 to 18: 8 to 10 hours

During adolescence, the body still needs plenty of rest, even as bedtimes start to get later. Between the ages of 13 and 18, the recommended amount of sleep is 8 to 10 hours per night.

Hours of sleep are a guideline, not a strict goal

Knowing the recommended amount of sleep for each age group helps guide sleep schedules, but the quality of sleep also matters. Two children may sleep the same number of hours and wake up feeling very different.

Instead of just looking at the clock, pay attention to how your child starts the day. Do they wake up full of energy? Do they maintain a level of attention and energy appropriate for their age? Do they often need to catch up on a lot of sleep over the weekend? These signs can help you determine whether sleep is truly fulfilling its purpose.

The bedroom should adapt to each stage of growth

As the body grows, so do the needs for space, support, and comfort. A suitable sleeping environment should be simple, peaceful, and age-appropriate, starting with a sleeping surface that adapts to the child without compromising stability or breathability.

The Bambino Children's Mattress was designed for children ages 2 to 14 and combines high-quality foam with a layer of memory foam. It is a solution designed to support children through different stages of growth, offering support, comfort, and breathability.

In the early years, your choice should always follow age-appropriate safety recommendations. Later on, the focus also shifts to comfort, the size of the bed, and the ability of the sleep system to adapt to changes in the body.

What can interfere with sleep even when you seem to be getting the right amount of sleep?

A child may stay in bed for the recommended amount of time and still not get restful sleep. Frequent awakenings, excessive heat, noise, light, very irregular sleep schedules, or intense stimuli before bedtime can interfere with uninterrupted sleep.

It’s also worth paying attention to signs such as persistent snoring, breathing through the mouth at night, waking up repeatedly, or experiencing significant daytime sleepiness. In these cases, the issue may go beyond sleep habits.

The goal is not to monitor every night in minute detail, but to recognize patterns. When a change persists and begins to affect the child’s well-being, learning, or energy levels, it should be evaluated by a healthcare professional.

How can you help a child find their own rhythm?

The body responds well to routine. Relatively regular schedules, a calmer transition at the end of the day, and a bedroom associated with rest help the child recognize that it’s time to go to sleep.

Rather than creating a long or perfect routine, look for small habits that are easy to repeat: limit screen time before bed, dim the lights, keep your bedroom comfortable, and set aside the last few minutes of the day for relaxing activities.

 

At Leafsleep, we believe that good sleep starts with creating an environment where the body can rest naturally. A quiet bedroom, consistent routines, and a sleep system tailored to a child’s stage of development help turn sleep hours into true recovery time.
