Bedtime Calculator and Routine Chart Maker

How to use the bedtime calculator

If you are asking, “What time should my child go to bed?”, start with the time your child needs to wake up. Choose their age group and enter that wake-up time in the calculator. For a child under 6, enter their total daytime nap time as well.

The tool shows a bedtime window based on the recommended sleep range for that age. Read the result as a window for when your child should be asleep, rather than when the bath or bedtime book should begin. Set the wind-down start time earlier so the routine has room to happen.

A range gives you room to choose a bedtime that fits your child and household. If the later end would leave your child with less sleep than they seem to need, consider the earlier, more generous part of the window. You can change the inputs when your child’s wake-up time or naps change.

• Pick your child’s age group.
• Enter the wake-up time you are planning around.
• For children under 6, add total daytime nap time.
• Use the result to plan when sleep begins, then build the routine leading up to it.

How much sleep does a child need by age?

The American Academy of Sleep Medicine recommends the following sleep amounts per 24 hours for healthy children. The American Academy of Pediatrics has publicly supported these recommendations. For infants and children through age 5, the totals include naps.

These are ranges, so the calculator does not present one bedtime as the answer for every child of the same age. Use your child’s age to find the relevant range, then consider wake-up time and any daytime sleep. If you are concerned about your child’s sleep, your pediatrician can help you discuss what is happening.

• Infants 4 to 12 months: 12 to 16 hours, including naps.
• Ages 1 to 2 years: 11 to 14 hours, including naps.
• Ages 3 to 5 years: 10 to 13 hours, including naps.
• Ages 6 to 12 years: 9 to 12 hours.
• Teens 13 to 18 years: 8 to 10 hours.

Turning sleep need into a bedtime

To turn a sleep range into a bedtime window, begin with the planned wake-up time and count backward by the sleep needed at night. For children under 6, the calculator subtracts the nap time you enter from the recommended 24-hour total first. This keeps daytime sleep in the calculation without treating it as nighttime sleep.

For example, a 4-year-old who wakes at 7:00 a.m. and naps 1 hour needs 9 to 12 hours of sleep at night. Counting back from wake-up time points to falling asleep between 7:00 p.m. and 10:00 p.m. Families usually aim for the earlier, more generous part of that window.

The calculated time is an asleep time. If you want to include a bath, pajamas, toothbrushing, a book, and a goodnight, begin those steps before the selected asleep time. The routine chart helps you place those activities in an order your child can follow.

• Start with age and the planned wake-up time.
• For a child under 6, account for daytime naps.
• Choose an asleep time within the resulting window and begin winding down earlier.

Build a bedtime routine that sticks

A calm, predictable routine gives the evening a familiar order. The American Academy of Pediatrics’ HealthyChildren.org guidance favors keeping the same steps in the same order each night. Choose steps that fit your family, then arrange them in the chart as you expect to do them.

You can include a bath, pajamas, brushing teeth, a toilet visit, a book, a hug, and lights out. Add custom steps if your child’s routine needs them, and reorder the pictures until the sequence makes sense. Set a wind-down start time that leaves space for the routine before the asleep time you chose.

Keep screens off before bed and make room for a book or quiet talk. At the end, use a short goodnight and leave calmly. The chart is a prompt for that sequence, so you can return to the same order when an evening feels busy.

• Put the steps in the order you plan to use each night.
• Keep the winding-down portion calm.
• Let the final steps lead toward a short goodnight and lights out.

Using a picture chart with toddlers and preschoolers

A toddler bedtime routine chart puts the evening’s steps where your child can see them. Build the picture-style chart with familiar activities, then print it for use during the routine. No signup is needed to make or print a chart.

Show your child the next picture as you move through the routine. The images can help you point to what comes next without changing the order of the evening. A preschooler can also follow along as you move from getting ready to the book, goodnight, and lights out.

Keep the chart aligned with what you actually do. If your family reads before a hug, place the pictures that way; if a custom step belongs between pajamas and brushing teeth, move it there. A chart is most useful when it reflects a calm sequence you can repeat.

• Choose the pictured steps your family uses.
• Add and reorder custom steps where they belong.
• Print the bedtime routine chart and use it as a visual guide.

Adjusting bedtime and knowing when to ask for help

If naps change, update the nap time in the calculator for a child under 6 and look at the bedtime window again. The recommended total includes daytime sleep for these ages, so a different nap entry changes how much of that total remains for nighttime. Keep the planned wake-up time current, too.

Daylight saving time or a new school start can change the wake-up time you are planning around. Enter the wake-up time your child now needs, review the resulting asleep window, and set the wind-down start time to match. You can keep the chart’s familiar order while adjusting when the routine begins.

The sleep ranges are for healthy children and are general guidance, not medical advice. Talk with your child’s pediatrician about snoring, frequent night waking, breathing pauses, or daytime sleepiness that worries you. The calculator and chart can help you describe your current schedule, but they cannot assess a sleep concern.

• Revisit the calculator when wake-up time or naps change.
• Move the wind-down start time with the asleep time you choose.
• Ask your pediatrician about sleep symptoms that concern you.
