Toddlers between the ages of 1 and 2 need 11 to 14 hours of total sleep per day, including naps. Children ages 3 to 5 need slightly less, around 10 to 13 hours. These ranges, endorsed by the American Academy of Pediatrics, cover the full 24-hour period, so nighttime sleep and daytime naps both count toward the total.
How Those Hours Break Down
Most toddlers get the bulk of their sleep at night, typically 10 to 12 hours, with the remaining hours filled by one or two daytime naps. A younger toddler (around 12 to 18 months) often still takes two naps a day, one in the morning and one in the afternoon, each lasting roughly 1 to 2 hours. Between 18 and 24 months, most children drop the morning nap and shift to a single afternoon nap.
That transition doesn’t happen overnight. You may notice your toddler resisting the morning nap, taking longer to fall asleep for it, or staying awake through it entirely. These are normal signals that they’re ready to consolidate into one nap. During the adjustment, some days will still be two-nap days and others won’t. It usually sorts itself out within a few weeks.
Why the Range Is So Wide
Three hours is a big gap between 11 and 14. That’s because individual sleep needs genuinely vary from child to child. Some toddlers function well on 11 hours total, while others are clearly undertired at bedtime because they’re already getting 14. The right number for your child is the one where they wake up fairly easily, stay in a reasonable mood during the day, and fall asleep within about 15 to 20 minutes of lights out. If your toddler consistently lands below 11 hours and seems fine, that’s worth mentioning to your pediatrician, but it isn’t automatically a problem.
Signs Your Toddler Isn’t Sleeping Enough
Toddlers who are short on sleep rarely look sleepy the way adults do. Instead, they tend to speed up. Common signs of an overtired toddler include increased activity and hyperactivity, clinginess, crying or whining more than usual, clumsiness, demanding constant attention, losing interest in toys quickly, and becoming fussy about food. Paradoxically, an overtired toddler can also have a harder time falling asleep, which creates a frustrating cycle: the less sleep they get, the more wired they seem at bedtime.
If you’re seeing these patterns regularly, especially in the late afternoon or around bedtime, it’s worth shifting the schedule earlier rather than later. Even a 15- to 30-minute change in bedtime can make a noticeable difference within a few days.
Sleep Regressions at 18 and 24 Months
Just when you think you’ve figured out your toddler’s sleep, a regression can throw everything off. The most common ones happen around 18 months and again near 24 months, and they’re closely tied to the nap transition. When a toddler is getting ready to drop a nap, they accumulate less “sleep pressure” during the day. That means they aren’t as tired at bedtime, so they fight falling asleep, call out for you repeatedly, or wake up in the middle of the night.
The good news is that these regressions are typically brief, often less than a week. They feel longer than they are. The key is to stay consistent with your routine rather than introducing new sleep habits (like lying down with your toddler or bringing them into your bed) that you’ll need to undo later.
Building a Bedtime Routine That Works
A consistent bedtime routine is one of the most reliable ways to improve how quickly your toddler falls asleep, how long they stay asleep, and how often they wake during the night. A large cross-cultural study of over 10,000 families found a dose-dependent relationship: the more nights per week a family followed a bedtime routine, the better the child’s sleep. That included earlier sleep onset, fewer night wakings, and more total sleep time. Even night-to-night consistency matters. Research on toddlers specifically found that how closely the routine was followed on any given night predicted how long the child slept that night.
The routine itself doesn’t need to be elaborate. A predictable sequence of activities in the hour before lights out is what matters. A bath, putting on pajamas, reading a book or two, a brief cuddle, and then into the crib or bed is a classic sequence that works for most families. Storytelling, singing, or a few minutes of quiet conversation all serve the same purpose: they signal to your toddler’s brain that sleep is coming. Aim to keep the routine to about 20 to 30 minutes. Longer routines tend to invite stalling.
Screens and Sleep
Screen use in the hour before bed can make it harder for toddlers to fall asleep in two distinct ways. First, the content itself raises alertness and heart rate, even if it seems calm to you. Second, the light emitted by screens disrupts production of melatonin, the hormone that tells the brain it’s time to sleep. Toddlers are more sensitive to this effect than adults because their eyes let in more light. Turning off screens at least an hour before bedtime gives melatonin levels a chance to rise naturally.
Setting Up the Sleep Environment
A cool, dark, quiet room supports the longest stretches of sleep. Keep the bedroom at a consistently cool but not cold temperature. Blackout curtains or shades help, especially in summer months when the sun sets well after a toddler’s ideal bedtime. White noise machines can buffer household sounds and street noise, but keep the volume moderate and place the machine across the room rather than right next to the bed.
If your toddler has recently transitioned from a crib to a toddler bed, expect a few weeks of adjustment. The novelty of being able to get out of bed is exciting, and most toddlers will test that freedom. A calm, boring response to repeated curtain calls (walking them back to bed with minimal conversation) tends to resolve this faster than negotiation or frustration.
Sample Sleep Schedules by Age
- 12 to 15 months: Two naps (mid-morning and early afternoon) totaling 2 to 3 hours, plus 10 to 12 hours of nighttime sleep. Bedtime around 7:00 to 7:30 p.m.
- 15 to 18 months: Transitioning from two naps to one. Some days will still need two shorter naps. Bedtime may need to shift earlier on one-nap days.
- 18 to 24 months: One afternoon nap of 1.5 to 2.5 hours, typically starting between 12:30 and 1:00 p.m. Nighttime sleep of 10 to 12 hours. Bedtime around 7:00 to 8:00 p.m.
- 2 to 3 years: One afternoon nap of 1 to 2 hours. Total daily sleep drifting toward 11 to 13 hours. Some children begin dropping the nap entirely closer to age 3.
These are starting points, not rigid prescriptions. Your toddler’s wake windows, mood, and how easily they fall asleep will tell you more than any chart. Adjust bedtime and nap timing based on what you observe, and give any schedule change at least 5 to 7 days before deciding whether it’s working.
