Why Your Child's Perfect Bedtime Might Not Be 7 p.m. After All

It's no secret that kids need more sleep than adults—their bodies and brains are still growing, after all. That's why so many parents aim to enforce strict bedtime rules, and a 7 p.m. lights-out is often considered the gold standard. But who decided that, anyway?

Turns out, the seven-to-seven sleep schedule (as in: asleep by 7 p.m., awake by 7 a.m.) has just as much to do with daily routines as it does with science. "A 7 p.m. bedtime gives families space to reconnect after work or school, enjoy dinner together, and then have a little breathing room after the kids are tucked in," explains pediatric sleep consultant Diana Zales. "Plus, in most parts of the year, it's already dark by then, which aligns with kids' natural circadian rhythms."

So is 7 p.m. a biologically perfect bedtime, or just a helpful parenting strategy? Let's unpack where the rule came from, what the science actually says and the best way to create a routine that works for your family—not the clock.

Why the 7 p.m. bedtime is a popular idea (and sometimes works)

So, where did the 7 p.m. bedtime even come from? Zales traces it back to something simple: the 7-to-7 schedule (as in asleep by 7 p.m., awake by 7 a.m.). "Children in their early years typically need 11 to 12 hours of sleep," she says. "A 7 o'clock bedtime allows for a natural 7 a.m. wakeup, which means they're well-rested and ready for daycare, school or just in life in general. For parents, it also keeps mornings calm instead of chaotic."

The science behind early bedtimes

"Light and darkness signal to the body that it is time to be awake or asleep," Zales explains. "This is especially true in the first few months, when a baby's circadian rhythm is still developing. When bedtime happens during natural darkness,  babies are more likely to fall into a restful, consistent pattern."

The power of routine

Timing matters, but so does the ritual surrounding it, Zales says. "The more consistent we are with bedtime, lighting, and a calming routine, the easier it is for babies to differentiate between day and night."

As babies grow, their wake windows naturally get longer, so bedtimes can shift later—but be careful. "In those early months, routine is everything. It's what helps their bodies sync up with their environment," Zales says.

When an early bedtime actually helps

Not every kid needs to be in bed at 7 p.m. sharp, and that's okay. Still, Zales points out that for some children, earlier can be better. "For instance, if the child is still in the napping age, or just starting to drop naps, an earlier bedtime can actually help improve sleep quality," she says. "Putting a child to bed overtired can make it more difficult for them to fall asleep, stay asleep and get themselves back to sleep. In those cases, a slightly earlier bedtime might help kids sleep longer."

Myth: All children have the same sleep needs

While all humans operate on a circadian rhythm—and syncing with it helps improve the quality of sleep—certified sleep consultant Meg O'Leary says there’s no universal bedtime for kids. "Children’s optimal bedtimes depend on a mix of factors: their age, nap schedule and internal body clock," she explains. "For instance, a 2-year-old who still naps in the afternoon will likely need a much later bedtime than a 4-year-old who's dropped naps altogether."

Instead of anchoring sleep to a specific clock time, O'Leary recommends a more intuitive approach: Start by working backward from your child's wake time, making sure they're getting the total hours of sleep recommended for their age group (more on that below). Then, adjust from there.

"Pay close attention to when your child naturally starts showing signs of tiredness," says O'Leary. "Learn their sleep cues, and aim to get them to bed before they hit that over-tired wall."

Recommended benchmarks for age-based sleep

While every child is different, O'Leary notes that there are age-based benchmarks parents can refer to when figuring out just how much sleep their child needs. "These guidelines can be a helpful starting point," she says.  "Just keep in mind that overnight sleep should be prioritized, with naps filling in the rest as needed—especially for younger children."

Here's a quick breakdown of recommended sleep totals by age group.

• 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-age children (6 to 12 years): 9 to 12 hours

• Teens (13 to 18 years): 8 to 10 hours

Don't assume your child has low sleep needs

Every child's sleep needs can vary within the typical age ranges, but O'Leary cautions parents against assuming their child has “low sleep needs” when bedtime becomes a struggle. "In many cases, children who aren't getting enough rest don't actually need less sleep," she explains. "They're simply missing the skills to fall asleep on their own and stay asleep through the night."

Another common misconception? That all sleep should happen at night. In reality, O'Leary notes that sleep needs are better measured over a 24-hour period, especially for babies and toddlers. "We always encourage parents to aim for about 11 hours of nighttime sleep, since that's when restorative rest happens," adds O'Leary. "The rest comes from naps, which can vary a lot depending on age. A 2-year-old might nap for 45 to 75 minutes, while a 4-month-old could need anywhere from three to four and a half hours of daytime sleep."

Fact: Individual differences and chronotypes matter

Chronotypes

We all know that sleep is essential, but what many don't realize is how deeply personal it can be. According to pediatric sleep consultant Tali Rasis, it comes down to your child's chronotype—or in simpler terms, their internal body clock. "Some kids feel wired and awake even when it's dark outside, while others are already winding down and ready to hit the pillow," she says. "When you align sleep with your child's natural rhythm, bedtime becomes smoother and less of a battle."

Temperament and energy levels

While a child's temperament doesn't affect how much sleep they need, it influences how you approach bedtime—especially once toddlerhood kicks in and the stalling begins, O'Leary says. "I have four kids, and each of them has a completely different personality. Bedtime looks a little different for each one," she shares. "An easygoing child might settle more quickly at the end of the day, while a high-energy or strong-willed child may need a longer wind-down routine to help their bodies and brains transition to sleep."

Still, no matter your child’s personality, O'Leary stresses that helping them relax with repeatable sleep cues can signal that bedtime is near. "The key is consistency," she says. "Every child can learn to love sleep when bedtime feels predictable and calm."

Growth spurts

Growth spurts and developing new skills (like rolling, crawling or walking) can temporarily disrupt sleep, but they’re also a sign that your child is developing and should be celebrated. "Often growth spurts come with increased hunger and physical discomfort, both of which cause nighttime wakings," says O'Leary. "Babies and toddlers also tend to 'practice' new skills in their sleep, which can cause them to wake more frequently as their brains process new information."

Physical growth or developmental changes can also temporarily increase your child's sleep needs. "This is because the body produces growth hormones during sleep, so the need for more sleep often goes hand in hand with a growth spurt," she adds.

How family lifestyle and dynamics influence bedtime flexibility

Impacts of work schedules and activities on bedtime

Family lifestyle and dynamics influence how flexible bedtime can be, and that includes work schedules.

"If a parent is working late and doesn't get home until it's time for bed, bedtime routines may be shorter or rushed, or bedtime could be pushed later," Zales says. "In these instances, I recommend a later wake-up time to ensure the child gets enough rest.

After-school activities may also compress the bedtime routine. According to Zales, "If activities are close to bedtime, the child may be too stimulated to fall asleep immediately and could have trouble settling down. Seeing parents for the first time after a long day can also be stimulating and may lead to a prolonged bedtime routine, as the child wants to spend quality time with the parent."

Cultural differences in sleep routines

Cultural differences in sleep routines also impact what bedtime looks like. "In some cultures, it's customary for children to sleep in bed with parents, and in others, children typically have their own sleep space or their own room," Zales shares.

Timing is also a big difference across countries. "For instance, the 7 p.m. bedtime may be more common in America, but in countries like Spain, India, and Japan, bedtime could be closer to nine to ten p.m. Sleep space, bedtime routines, and bedtimes are also largely impacted by what is most important to the culture."

Importance of family time before bed

"Family connection time is important in helping a child feel safe and comfortable by strengthening the emotional bond with their parents," explains Zales. "As a sleep consultant, I recommend as much family time during the bedtime routine as possible, whether that's through bathtime, reading books, family dinner, or cuddles before bed. By adding family time into the routine, the child will be able to unwind, communicate freely, and feel really calm going into bedtime, which will help them fall asleep and stay asleep."

How to create a flexible, effective bedtime routine

Be consistent

For a bedtime routine your kids will actually stick to, consistency is crucial, according to Dr. Amiirah Aujnarain, MD, FAAP, a board-certified pediatrician.

"Children thrive on predictability," she shares. "A consistent sequence of calming activities—like a bath, pajamas, story, and then bed—signals to their body and brain that it's time to wind down for sleep. This process helps regulate their internal clock and prepares them for rest."

Rather than sticking to a strict bedtime, which can lead to stress if the night runs late or your child isn't tired yet, Aujnarain suggests that consistency in the routine is far more effective. "This offers the flexibility families need while still reinforcing healthy sleep cues," she adds.

Components of a wind-down routine

Aujnarain says that the perfect wind-down routine is all about what works for your child. But there are a few key elements she suggests making non-negotiable:

• Calm and predictable: Stick to the same sequence every night to create predictability.
• Screen-free: Avoid TVs, tablets, and phones at least one hour before bed.
• Soothing activities: Opt for calming activities like a warm bath, reading, cuddling, or soft music.
• Ease into rest: Dim the lights and lower your voice to help signal to your child's body that it is time to start producing melatonin.

Creating the optimal sleep environment

Creating the optimal sleep environment is just as important, says Aujnarain. "It can make all the difference in how well your child sleeps at night."

To get it right, aim for a cool, dark, and quiet room. "Blackout curtains, white noise if needed, and a comfortable, sleep-only bed are essential," she suggests. "Keep screens and stimulating toys out of the bedroom. For younger kids, a nightlight or a comforting stuffed animal can provide security."

How to recognize signs of insufficient sleep and when to seek help

Signs your child is not getting enough sleep: 

Kids need proper sleep to stay healthy, so if signs of sleep struggles appear, Aujnarain says that it is important to get extra help. Not sure if your child is getting enough rest? Here are some common signs to look out for:

• Difficulty waking up in the morning or needing to be woken multiple times.
• Daytime mood changes like crankiness, hyperactivity, or irritability.
• Trouble focusing or learning, which could lead to sleep deprivation.
• Frequent yawning or rubbing their eyes, especially during the day.
• Falling asleep in the car or during quiet activities, like watching TV or reading.

How chronic sleep deprivation impacts health and development: 

Sleep deprivation can significantly impact your child's health and development. According to Aujnarain, there are several key warning signs to keep an eye on:

• Mood and behaviour: Increased irritability, tantrums, or signs of anxiety.
• Learning and attention: A noticeable dip in school performance or focus.
• Growth: Deep sleep is when growth hormone is released, so less sleep could affect growth.
• Immune system: A weakened immune system, leading to more frequent illnesses.
• Metabolism: A higher risk for weight gain, along with potential long-term cardiovascular issues.

When to see the doctor: 

If you suspect your child isn't getting enough sleep at night, Aujnarain recommends reaching out to your doctor. It's always better to get guidance if you are concerned, especially in these situations.

• Sleep issues lasting more than 2–3 weeks, despite maintaining consistent routines.
• Snoring, gasping, or pauses in breathing could be signs of sleep apnea.
• Daytime behavioural or learning concerns that are linked to poor sleep.
• Persistent bedtime resistance, night terrors, or insomnia that don't seem to improve.

The bottom line

While sleep is undeniably important, Rasis emphasizes that there's no universal "right" bedtime for every child. "Kids are individuals," she says, stressing that the best bedtime is one that aligns with a child's unique rhythm, taking into account both biological and environmental factors.

For parents looking to ensure their kids are getting enough rest, establishing—and sticking to—a consistent routine is key. "Children are creatures of habit—they crave routine and predictability," Rasis notes. "A well-established bedtime routine serves as a signal to their body and mind that it's time to wind down, which ultimately makes the process easier for both parents and children."

When it comes to crafting a sleep schedule that works for your family, Rasis advises focusing on the child first, not the charts. "With so many conflicting sleep advice out there, it's easy to feel overwhelmed as a parent," she acknowledges. "But what matters most is finding what works for you and your child. And if you need extra support, don't hesitate to contact your pediatrician or a certified sleep consultant for guidance."
