Part 1. Sleep Chart by Age: How Much Sleep Do Babies Need

It is widely acknowledged that infants require more sleep than adults, teenagers, and even toddlers. However, many people may not be aware of the specific hours of sleep that babies need. The following age-based sleeping chart provides valuable information about the recommended sleep durations for kids of various ages. By referring to this chart, you can easily determine the appropriate amount of sleep for your kids:

Babies aged 0-3 months generally need 14 to 17 hours of sleep per day, including naps and nighttime sleep. As for infants from 4-12 months, they still require 12 to 16 hours. Toddlers and preschoolers typically need 9 to 14 hours of sleep. As children reach their teenage years, their sleep needs decrease to around 8 to 10 hours, similar to adults.

Understanding these sleep durations is vital for supporting children’s growth and well-being. With further development and as children approach their teenage years, their sleep requirements continue to decrease. 

Having sleep durations longer or shorter than the recommended times for their age group can have negative effects on children. Sleep deprivation can weaken their immune system, hinder growth and development, contribute to emotional instability, impact social interactions, and compromise physical safety. Oversleeping can cause decreased productivity, disrupted sleep patterns, social isolation, and a potential negative impact on mental health. It’s crucial to find a balance and ensure children get the appropriate amount of sleep for their age to promote their well-being and healthy development. 

Part 2. Sleep Deprivation: Symptoms of Lacking Sleep in Children

Getting too little sleep will result in behavioral and cognitive issues: Kids will have more difficulties with concentration, emotional controls, problem-solving, reasoning, and more. If you find that your kids have these symptoms, it is highly possible that your kids are having a lack of sleep:

1. Symptoms of Sleep Deprivation in Kids

Sleep deprivation can have impacts on kids both mentally and physically.

2. Causes of Sleep Deprivation in Kids

Adequate sleep is vital for a child’s physical, cognitive, and emotional development, yet many children struggle to obtain the recommended amount of restful sleep each night. Exploring the causes behind this widespread issue is crucial to addressing and mitigating the negative effects of sleep deprivation on children’s overall well-being:

2.1. Excessive Screen Time and Electronic Devices

Excessive screen time and electronic device usage are major contributors to sleep deprivation in children. The blue light emitted by screens can interfere with the production of melatonin, the hormone responsible for regulating sleep. This can disrupt their sleep-wake cycle and make it difficult for them to fall asleep. Setting screen time limits for children is crucial in managing their exposure to electronic devices, especially before bedtime. By reducing screen time and encouraging alternative activities, such as reading or engaging in creative play, parents can help improve their child’s sleep quality.

2.2. Academic and Extracurricular Demands

Academic and extracurricular demands also play a role in sleep deprivation among children. With increasing academic workload and participation in various activities, children may struggle to find a balance between their commitments and sufficient sleep. Homework and study time management are essential in ensuring that children have enough time to complete their assignments without sacrificing sleep. Parents can support their children by helping them prioritize tasks, create a study schedule, and advocate for reasonable academic expectations.

2.3. Sleep Environment and Bedroom Factors

The sleep environment and bedroom factors also contribute to sleep deprivation in children. Noise and light pollution in the bedroom can disrupt sleep and make it challenging for children to achieve restful slumber. Parents can minimize noise disturbances by using white noise machines or toy projectors that offer calming scenes with soft, dimmable lighting and can ensure that the bedroom is adequately darkened and quiet to create a conducive sleep environment. Creating a calm and comfortable sleep environment with comfortable bedding and an appropriate mattress can also contribute to better sleep quality for children.

Part 3. Symptoms of Sleep Disorders in Children

Even though sleep deprivation and sleep disorders share diverse similarities, they have diverse differences: Sleep deprivation is often a temporary condition caused by external factors, while sleep disorders are clinical conditions that may require medical intervention. Sleep disorders can significantly impact the health and functioning of children, impairing cognitive function, contributing to behavioral and emotional issues, causing excessive daytime sleepiness, affecting social interactions, and potentially impeding developmental progress. Therefore, it is crucial to spot sleep disorder from an early stage and stop it from getting worse. In the next paragraph, I will share with you several common symptoms you can tell your children are suffering from sleep disorders:


1. Trouble Sleeping: If a toddler sleeps issues happen to your kids, that he/she is not willing to go to sleep is a sign of insomnia. Insomnia can be caused by stress from school work, social issues, family issues, and more.

2. Snoring: Snoring which is a vibration in the upper airway is not a big deal directly for kids’ health, however, it is a precursor to a sleep disorder in children.

3. Nightmares: Having a nightmare at night will wake a child up feeling terrified, afraid, and threatened. Nightmares happen a lot when your kids are 3-10 years old and will get less as your kids grow. Frequently waking up at night can disturb children’s sleep and lead to behavioral issues.

4. Night Terrors: Night terrors are different from nightmares. There are terrifying scenes in kids’ dreams but that won’t wake your kids up. Symptoms are sometimes the child sitting up in bed, sweating, rapid breathing, and the eye wide open without waking up. The cause of night terrors is considered something to do with the immature central nervous system.

5. Sleep Walking: More than 30% of kids aged 3-7 are having sleepwalking issues while sleeping. Kids unintentionally leave their beds and walk around with their eyes open. Sleepwalking occurs for about 5 to 15 minutes and they have no memory of this when they wake up the next morning. Sleepwalking is dangerous when they are walking downstairs. Do not wake up a sleepwalker because it will cause fear and confusion.

6. Bedwetting: Bedwetting at night doesn’t raise concerns of parents because bedwetting is common among kids. However, if your over 5-year-old kids wet their beds at night for more than 2 times a week, then that’s a symptom of sleep disorder.

Sleep disorders encompass symptoms such as difficulty falling asleep or staying asleep, abnormal sleep patterns, disrupted breathing during sleep, sleep-related movements or behaviors, and other disorder-specific symptoms.

Part 4. Causes & Effects of Kids’ Oversleeping

If your 4-year-old kid has sleeping 14 hours a day and is still tired, then he/she has a oversleep. If this happens frequently, it is not a good thing because there are some side effects of excessive sleeping which will do harm to your kids’ health if you don’t stick to the sleep charts for kids. Let’s check the causes and effects of oversleeping:

1. Top 3 Oversleeping Causes: Reasons for Oversleeping

But if this happens regularly, that is real oversleeping.

If you don’t follow a strict sleep time schedule and stay up late at night or sometimes go to bed earlier. If your kids are having this sort of delayed sleep phase syndrome, the so-called DSPS, their internal body clocks will be chaotic and you will find it absolutely hard to wake them up even with a few alarm clocks being set.

c). A Poor Mindset
Anxiety, boredom, depression, fear, or lack of motivation will also lead to oversleeping. Think about it. Did you feel like not willing to get up, especially in winter? Did you feel sleepy the morning you have to get up early for the coming exam? Did you wish to bury yourself in bed and don’t want to think about the presentation on the weekend morning? If yes, then, that’s the same circumstance your kids are experiencing.


2. Mental & Physical Effects of Kids Oversleeping

b). Back Pain – That depends on the support of your mattress. Too soft will concentrate your body weight to the lower back and cause pain no matter if you sleep on your stomach, on your side, or on your back, while to firm will provide uneven support and cause you to toss and turn during the night.

When oversleeping happens a lot, it will do some effects on psychology as well. Being lecture not to be late to school next time, missing the beginning of the long-anticipating movie, and getting fat day by day because of oversleeping will grow anxiety, depression, and regret in kids.
