A 1-year-old needs 11 to 14 hours of sleep in a 24-hour period, including naps. Most 12-month-olds get about 11 to 12 of those hours at night and another 2 to 3 hours during the day, split across one or two naps.
Nighttime and Nap Breakdown
At 12 months, most babies are still taking two naps per day, with each nap lasting roughly 60 to 120 minutes. Together, those naps should add up to about 2 to 3 hours of daytime sleep. The remaining 11 to 12 hours happen overnight, ideally in one long stretch, though brief wakings are still normal at this age.
Somewhere between 12 and 18 months, most toddlers drop down to a single afternoon nap. A child who consistently fights the morning nap or takes a long time to fall asleep for it is probably ready to make that switch. Some kids in daycare settings transition to one nap earlier simply because the schedule requires it. Either pattern, two naps or one, is fine as long as total sleep stays within the 11-to-14-hour range.
What a Typical Day Looks Like
There’s no single “correct” schedule, but a common rhythm for a 12-month-old on two naps looks something like this: wake around 6:30 to 7:00 a.m., first nap mid-morning (around 9:30 or 10:00), second nap early afternoon (around 1:30 or 2:00), and bedtime between 7:00 and 8:00 p.m. The key variable is how long your child can comfortably stay awake between sleep periods, which at this age is typically 3 to 4 hours.
Once your toddler shifts to one nap, that nap usually lands right after lunch and runs 1.5 to 2.5 hours. Bedtime may need to move a bit earlier during the transition to keep total sleep on track.
Why These Hours Matter
Sleep does heavy lifting for a 1-year-old’s body and brain. During sleep, the body releases growth hormones, strengthens the immune system, and fights off infections. The brain uses sleep time to consolidate memories and process everything learned during the day, which is a lot at this age, when language, motor skills, and social understanding are all accelerating at once.
Consistently falling short on sleep makes it harder for toddlers to retain new information. It also disrupts mood regulation, which is why an overtired 1-year-old can seem inconsolable in a way that goes beyond normal fussiness.
Signs Your Child Isn’t Getting Enough Sleep
Overtiredness in a 1-year-old doesn’t always look like what you’d expect. Beyond the obvious cues like yawning and heavy eyelids, watch for:
- Clumsiness: tripping or falling more than usual
- Glazed, dull eyes or a vacant stare
- Irritability and restlessness that won’t resolve with food or comfort
- Comfort-seeking behaviors: suddenly clinging to a favorite toy, blanket, or thumb
- Becoming unusually quiet and still, as if they’ve “shut down”
If you’re seeing these signs regularly before nap or bedtime, your child may need an earlier sleep window. An overtired toddler actually has a harder time falling asleep, because the stress response kicks in and produces a second wind of alertness. Moving bedtime or naptime earlier by even 15 to 30 minutes can break the cycle.
The 12-Month Sleep Regression
Right around the first birthday, many parents notice sleep falling apart: more night wakings, shorter naps, or bedtime battles that didn’t exist a week ago. This is the 12-month sleep regression, and it’s driven by a collision of developmental changes happening at once.
The most common triggers include separation anxiety (which peaks as social awareness grows), physical restlessness from learning to walk or cruise, teething pain, and simple overstimulation from a world that’s suddenly much more interactive. Some toddlers also start having occasional nightmares around this age, though that’s less common.
The good news: it typically lasts only a few weeks. Keeping your existing sleep routine consistent through the regression, rather than introducing new habits, gives your child the best chance of snapping back to normal patterns quickly.
Sleep Environment at 12 Months
Even though your child is a year old, the American Academy of Pediatrics still recommends keeping loose blankets, pillows, stuffed animals, and bumpers out of the sleep space. A firm mattress with a fitted sheet remains the safest setup. If you’re worried about warmth, a wearable sleep sack is a safer alternative to a blanket.
Screen time before bed is also worth watching at this age. Light from screens suppresses the body’s production of melatonin, the hormone that signals sleepiness. Turning off screens at least 30 to 60 minutes before bedtime helps your toddler’s brain wind down naturally. A short, predictable bedtime routine (bath, book, lights out) works better than any gadget at cueing sleep.
