Bedtimes for Children: When to Go to Bed?

"When does my child actually have to go to bed?" - this question arises at the latest when getting up in the morning becomes a daily struggle. Many parents follow what friends or neighbors do and then wonder about tantrums in the late afternoon or a child who can't settle down for hours in the evening. Yet, the right bedtime can be deduced surprisingly easily: by counting backward from the necessary wake-up time. This article shows how much sleep children need at what age, how you can deduce a suitable bedtime from this, and what you can do if going to bed becomes a battle every evening.

The short answer: The appropriate bedtime is determined by the age-specific sleep requirement and the necessary wake-up time. Toddlers aged one to two years need 11 to 14 hours including naps, preschoolers 10 to 13 hours, school children 9 to 12 hours, and teenagers 8 to 10 hours. If a seven-year-old needs to wake up at 6:45 AM and requires about 10 hours of sleep, bedtime would be around 8:15 PM – plus 20 to 30 minutes for falling asleep. More important than the exact time is regularity, even on weekends.

How much sleep children really need

The following ranges correspond to the recommendations of international sleep societies and refer to the total sleep time in 24 hours, including naps. They are deliberately formulated as a range because individual needs vary considerably: two children of the same age can differ by two hours without either of them getting too little sleep.

Calculating bedtime backwards

The calculation is simple and works for all ages. First: When does your child need to wake up for the morning to go smoothly? Second: How much sleep do they need – initially, aim for the middle of the age range. Third: Subtract this number of hours and add 20 to 30 minutes for falling asleep. An example: Waking up at 6:45 AM, needing 10.5 hours of sleep, results in a sleep time from 8:15 PM – so the child should be in bed around 7:45 PM. Observe for one to two weeks afterwards: If your child wakes up on their own, without an alarm, and in a good mood in the morning, the time is right. If they need to be woken up daily and are in a bad mood, move bedtime forward in 15-minute increments. How much sleep people generally need is covered in the article How much sleep do I really need?

Why overtired children seem hyperactive

Many parents know the phenomenon: the later it gets, the wilder the child becomes. The reason is physiological. As fatigue increases, the body releases more stress hormones like cortisol and adrenaline to stay awake. This activation makes falling asleep even more difficult – a vicious circle. Therefore, letting a restless child stay up a little longer until they are "really tired" usually doesn't help. The opposite is more effective: moving bedtime forward by 15 to 30 minutes. Typical signs of overtiredness include rubbing eyes, clumsy movements, whining over small things, and paradoxically, a sudden burst of energy. Knowing these signs allows you to use the window of time when falling asleep is easy.

An evening routine that works

Children are less guided by the clock than by routines. A 30 to 45-minute routine with the same sequence every time reliably signals that the day is ending: dinner, bath, brushing teeth, pajamas, two stories, dimmed lights, goodnight. Important are dim lighting in the last half hour and avoiding screens – tablets or television stimulate and delay melatonin release. Maintain the routine approximately the same even on weekends; deviations of more than an hour noticeably shift the rhythm. For preschool children, it's also worth looking at naps: If a four-year-old still naps for two hours in the afternoon, the evening sleep pressure will shift significantly later.

If it still doesn't work

Temporary difficulties are normal, especially around developmental leaps, starting kindergarten or school, and during family transitions. Clear, friendly boundaries are helpful: a consistent ritual, a limited number of stories, and calmly returning them to bed without long discussions. Also pay attention to the sleep environment – a cool, dark, and quiet room, as well as a suitable mattress, make a difference. You should consult a doctor for loud snoring with breathing pauses, pronounced leg restlessness, severe nocturnal anxieties lasting for weeks, or persistent daytime sleepiness despite sufficient sleep duration. For teenagers, the situation is different again, as the internal clock biologically shifts later during puberty – more on this in the article on sleep deprivation in teenagers.

Frequently Asked Questions about Children's Bedtimes

How do I find the right bedtime for my child?

Count backward from the necessary wake-up time: wake-up time minus age-appropriate sleep requirement, plus 20 to 30 minutes for falling asleep. Then observe for one to two weeks whether your child wakes up rested and in a good mood in the morning.

My child gets wilder in the evening – should I put them to bed later?

Often, the opposite is true. When overtired, the body releases stress hormones that keep you awake and make it harder to fall asleep. Try moving bedtime forward by 15 to 30 minutes and look for early signs of tiredness like eye rubbing or whining.

When can children give up naps?

Most children give up naps between the ages of three and five, with a wide individual variation. One sign is when the child falls asleep significantly later in the evening after napping, but still appears rested in the morning.

How strict should bedtime be on weekends?

Deviations of up to one hour are usually not a problem. More than that will noticeably disrupt the rhythm because the internal clock shifts, making Monday mornings correspondingly difficult. Keeping the wake-up time constant is more effective than keeping bedtime constant.

When should I seek medical advice for my child's sleep problems?

If there is loud snoring with breathing pauses, pronounced restlessness in the legs, severe nocturnal anxieties lasting for several weeks, or persistent daytime sleepiness despite sufficient sleep duration, a pediatrician should be consulted.
