A one-year-old needs 11 to 14 hours of total sleep per 24-hour period, including naps. This is the range endorsed by the American Academy of Pediatrics, and most toddlers in this age group land somewhere in the middle, around 12 to 13 hours combined. That total typically breaks down into a long stretch of nighttime sleep plus one or two daytime naps.
Nighttime Sleep vs. Naps
Most of your one-year-old’s sleep will happen at night, usually 10 to 12 hours. The remaining 1 to 3 hours come from daytime naps. At 12 months, many toddlers are still taking two naps per day, but most will drop down to a single nap by around 18 months.
If your child is on two naps, each one typically runs 45 minutes to an hour and a half. Once they consolidate to one nap, that single stretch often lengthens to fill the gap, landing around 1.5 to 2.5 hours in the early afternoon. The transition isn’t sudden. You’ll likely have a few weeks of inconsistency where some days have two naps and others only one.
Signs Your Toddler Is Ready for One Nap
The shift from two naps to one is one of the biggest sleep changes at this age, and it doesn’t always happen right at 12 months. Some children are ready at 13 or 14 months, others not until closer to 18 months. Watch for these patterns over a stretch of one to two weeks rather than reacting to a single off day:
- Resisting the second nap consistently, playing or babbling through it
- Skipping naps entirely despite being in a calm sleep environment
- Taking shorter-than-usual naps during one or both sleep windows
- Waking early in the morning or staying awake for long stretches in the middle of the night
One useful benchmark: if your child is regularly getting less than 10 hours of nighttime sleep while on a two-nap schedule, switching to one nap can help lengthen that overnight stretch. Dropping the second nap creates more sleep pressure by bedtime, which often results in faster sleep onset and fewer night wakings.
Why Sleep Cycles Look Different at This Age
One-year-olds cycle through the same sleep stages adults do (light sleep, deep sleep, and REM), but their cycles are shorter and they spend a larger proportion of the night in REM sleep. That’s the stage linked to learning and memory, which makes sense given how rapidly a toddler’s brain is developing.
Shorter cycles mean more transitions between stages, and those transitions are where brief wakings happen. It’s normal for a one-year-old to stir, shift position, or even cry out briefly before settling back down. Deep sleep, the most physically restorative stage, is also when sleepwalking, night terrors, and bedwetting can occur in older children. At 12 months these are uncommon, but you may notice your child seeming confused or groggy if you wake them during a deep sleep phase.
The 12-Month Sleep Regression
Right around the first birthday, many parents notice sleep suddenly falls apart. A child who was sleeping through the night starts waking again, fighting naps, or taking much longer to fall asleep. This is the 12-month sleep regression, and it’s driven by a collision of developmental milestones happening at once.
Your toddler may be learning to walk, which makes their body restless and overstimulated. Separation anxiety peaks around this age as social awareness grows. Teething pain from molars can add discomfort. And the nap schedule itself may be shifting, creating temporary misalignment between when your child is tired and when sleep is offered. The good news: this regression typically resolves within a few weeks without any major intervention. Keeping your routine consistent through it is the most effective strategy.
Bedtime Timing
Most toddlers do best with a bedtime between 6:30 and 7:30 p.m. That window aligns with their natural rise in sleepiness in the early evening. A child who napped well during the day can usually handle the later end of that range; one who had short or skipped naps may need to go down closer to 6:30 to avoid becoming overtired.
Overtiredness is counterintuitive but real. A toddler who misses their sleep window often gets a second wind fueled by stress hormones, which makes it harder for them to fall asleep and stay asleep. If bedtime battles are a regular problem, moving bedtime 15 to 30 minutes earlier for a few days can reveal whether the timing was the issue all along.
Creating a Safe Sleep Space
At 12 months, sleep surface safety still matters. Your child’s mattress should be firm, flat, and covered only with a fitted sheet. Soft items like pillows, stuffed animals, crib bumpers, blankets, and comforters are linked to suffocation and entrapment injuries, even at this age. Weighted blankets and weighted swaddles also pose risks and should stay out of the crib.
Room temperature plays a role in sleep quality too. A cool room (around 68 to 72°F) helps the body’s natural temperature drop that triggers sleepiness. If you’re worried about your child being cold without a blanket, a wearable sleep sack is a safe alternative that keeps them warm without loose fabric. Car seats, strollers, and bouncers are not recommended as regular sleep spaces, even for naps.
When Sleep Falls Outside the Range
The 11-to-14-hour guideline is broad for a reason. Some one-year-olds genuinely need closer to 11 hours and function perfectly well. Others need the full 14. What matters more than hitting an exact number is how your child behaves during awake hours. A well-rested toddler is generally in good spirits after waking, can focus on play, and doesn’t melt down at every small frustration.
Consistently falling below 10 hours of total sleep, or regularly sleeping more than 15 to 16 hours, is worth paying attention to. So are patterns like loud snoring, pauses in breathing during sleep, or a child who seems exhausted despite sleeping a normal number of hours. These can point to conditions like sleep apnea or other issues that disrupt sleep quality even when the quantity looks fine on paper.
