Sleep is essential for children's health and development. As children grow, their sleep needs change, and the amount of sleep they require decreases. Babies spend more time in REM sleep, which is important for learning and memory, and their sleep cycles are shorter than adults. As kids get older, the time spent in REM sleep decreases, and their sleep cycles get longer. By the time they start school, their sleep is similar to that of adults, with one complete sleep cycle lasting about 90 minutes.

What You'll Learn
REM sleep is important for learning and memory
While the amount of sleep children need varies depending on their age, it is important that they get sufficient REM sleep. REM sleep is important for learning and memory. Babies spend more time in REM sleep and their sleep cycles are shorter than adults. As children get older, the time they spend in REM sleep decreases and their sleep cycles get longer. By the time children start school, one complete sleep cycle lasts about 90 minutes, which is similar to an adult's.
REM sleep is characterised by rapid eye movement, faster breathing and a faster heartbeat. It is also the stage of sleep during which we have our most vivid dreams. While in REM sleep, we are unable to move our arms or legs.
During REM sleep, the brain consolidates information from the day, strengthening our memories and helping us retain what we have learned. This process is particularly important for children, whose brains are still developing.
In addition to its role in learning and memory, REM sleep is also thought to be the most refreshing stage of sleep. It is during this stage that the body releases hormones needed for growth and development.

Babies spend more time in REM sleep
Babies need a lot of sleep. As kids grow, their sleep needs decrease. While every child is different, experts recommend that infants aged 0–3 months get 14–17 hours of sleep, including naps. This decreases to 12–16 hours for infants aged 4–12 months, 11–14 hours for toddlers aged 1–2 years, and 10–13 hours for preschoolers aged 3–5 years. For kids of all ages, it's important to set up a bedtime routine that encourages good sleep habits.
Sleep is critical to children's overall health and development. Lack of sufficient sleep at a young age has been linked to problems with weight, mental health, behaviour, and cognitive performance.

Sleep needs decrease as children get older
Sleep needs do decrease as children get older. Babies need a lot of sleep, and as they grow, their sleep needs decrease. Toddlers between 1 and 2 years old should get between 11 and 14 hours of total sleep every day. By the time children start school, one complete sleep cycle lasts about 90 minutes, which is similar to an adult's. Sleep requirements for young children decline, and this is reflected primarily in a decreased amount of time spent napping during the day. However, sleep remains critical to their overall health and development. Lack of sufficient sleep at a young age has been correlated with problems with weight, mental health, behaviour, and cognitive performance.

Sleep is critical to overall health and development
Sleep is made up of two types of sleep: non-REM and REM (rapid eye movement) sleep. Together, these stages make up a sleep cycle. Babies spend more time in REM sleep, which is important for learning and memory, and their sleep cycles are shorter than adults. Time spent in REM sleep decreases and sleep cycles get longer as kids get older.
By the time kids start school, one complete sleep cycle lasts about 90 minutes, which is similar to an adult's. Stage 1 and stage 2 non-REM sleep are light sleep stages, where a person can wake up easily.
It's during the deeper sleep stage that the body releases hormones needed for growth and development. Lack of sufficient sleep at a young age has been correlated with problems with weight, mental health, behaviour, and cognitive performance.

Frequently asked questions
Kids need the most REM sleep, which is when we have our most vivid dreams. The younger you are, the more sleep you need.
This varies depending on their age. Infants (0-3 months) need 14-17 hours of sleep, while infants (4-12 months) need 12-16 hours. Toddlers (1-2 years) need 11-14 hours, and preschoolers (3-5 years) need 10-13 hours.
REM sleep is important for learning and memory. It's also when the body releases hormones needed for growth and development.
