A 1-year-old needs 11 to 14 hours of total sleep per 24-hour period, including naps. The American Academy of Pediatrics recommends this range for children ages 1 to 2 to support healthy growth and development. Most 12-month-olds land around 13 to 13.5 hours, split between a long stretch at night and two daytime naps.
How That Sleep Breaks Down
At 12 months, a typical day includes 11 to 12 hours of nighttime sleep and 2 to 3 hours of daytime sleep spread across two naps. That means the bulk of your child’s rest happens overnight, with naps filling in the gap. Some one-year-olds naturally sleep closer to 11 total hours and do perfectly well, while others consistently need the full 14. What matters most is that your child wakes up in a generally good mood and stays alert and engaged during wake time.
Wake Windows and Bedtime Timing
At 11 to 12 months, most toddlers can comfortably stay awake for about 3 to 4 hours between sleep periods. These stretches include feeding, play, and any wind-down time before the next nap or bedtime. If your child wakes at 6:30 a.m., for example, the first nap would fall around 9:30 or 10:00 a.m.
Working backward from your child’s wake windows helps you find the right bedtime. If the second nap ends around 3:00 p.m. and your child handles a 3.5-hour wake window before bed, a bedtime around 6:30 to 7:00 p.m. makes sense. A quiet wind-down routine before bed, like a bath followed by a book, signals that sleep is coming and helps the transition go more smoothly.
The Two-to-One Nap Transition
Your 1-year-old is likely still on two naps a day, but the shift to one nap is on the horizon. Most children are ready to fully drop to one nap between 14 and 18 months. It’s common for daycare providers to push this transition around 12 months, which can create some temporary overtiredness if your child isn’t quite ready at home.
Signs that the transition is approaching include:
- Resisting the second nap consistently, not just on occasional off days
- Skipping naps entirely while still seeming rested
- Taking unusually short naps when they previously slept longer
- Waking early in the morning or having long wakeful stretches in the middle of the night
If you’re seeing these signs only a few times a week, your child probably isn’t ready yet. The transition tends to go best when these patterns show up nearly every day for at least two weeks straight. Rushing it often backfires with a cranky, overtired toddler who sleeps worse, not better.
The 12-Month Sleep Regression
Right around the first birthday, many parents notice their previously solid sleeper starts fighting bedtime, waking at night, or refusing naps. This is the 12-month sleep regression, and it’s driven by a collision of developmental changes happening at once. Your child may be pulling to stand, cruising along furniture, or taking first steps, and that physical excitement makes it hard to settle down. Separation anxiety also tends to peak around this age, making your child protest when you leave the room at bedtime.
Teething plays a role too. Many 1-year-olds are cutting molars, and the discomfort can wake them at night or shorten naps. The good news is that this regression typically lasts only a few weeks. Staying consistent with your existing sleep routines, rather than introducing new habits like rocking or feeding to sleep, helps your child move through it faster.
Signs Your Child Isn’t Getting Enough Sleep
One-year-olds can’t tell you they’re tired, but their behavior makes it fairly obvious once you know what to look for. Early signs of tiredness include yawning, rubbing their eyes, staring blankly, and losing interest in toys or activities. You might also notice your child becoming clingy, fussy with food, or quick to cry over minor frustrations.
Overtiredness looks different, and it can be counterintuitive. Instead of slowing down, an overtired toddler often speeds up. Sudden bursts of hyperactivity, aggression over small changes, and intense resistance to sleep despite obvious exhaustion are all hallmarks. If you’re regularly seeing these signs, it usually means bedtime or nap time needs to shift earlier, or that wake windows have stretched too long.
Sleep Safety After the First Birthday
Turning one doesn’t automatically change crib safety rules. The AAP recommends keeping the crib bare: a firm mattress with a fitted sheet and nothing else. Pillows, blankets, stuffed animals, and crib bumpers all pose suffocation and strangulation risks. Many parents wonder when it’s safe to add a small blanket or lovey, and guidelines generally become more flexible after 12 months, but the safest approach is to keep the sleep space clear as long as possible. A sleep sack is a practical alternative that keeps your toddler warm without loose fabric in the crib.
The sleeping environment should also be free of dangling cords, electric wires, and anything your increasingly mobile child could reach from inside the crib. At this age, many toddlers can pull themselves to standing and lean over the rail, so checking that the mattress is at its lowest setting is worth doing if you haven’t already.
