A 1-year-old needs 11 to 14 hours of total sleep per 24-hour period, including naps. That recommendation comes from the American Academy of Sleep Medicine and remains the current pediatric standard. Most 12-month-olds split that time between a long stretch of nighttime sleep and two daytime naps, though the exact breakdown varies from child to child.
How the Hours Break Down
Of those 11 to 14 total hours, the bulk happens at night. A typical 12-month-old sleeps roughly 10 to 12 hours overnight, with the remaining 2 to 3 hours spread across daytime naps. Most babies at this age still take two naps a day, each lasting about 60 to 90 minutes. That pattern usually holds until around 18 months, when many toddlers consolidate down to a single nap.
A realistic daily schedule for a 12-month-old might look something like this: waking around 6:30 AM, a morning nap from about 9:45 to 10:45, an afternoon nap from about 2:15 to 3:15, and bedtime around 7:15 PM. The key spacing detail is that most babies this age need about 3.25 to 4 hours of awake time between sleep periods. If naps are too close together or too close to bedtime, you may see resistance at one or more of those sleep windows.
Why Sleep Matters So Much at This Age
Sleep does more than recharge your toddler’s energy. During deep sleep, the body releases a significant burst of growth hormone, particularly in the first stretch of slow-wave sleep shortly after your child falls asleep. That hormone surge drives physical growth, muscle development, and tissue repair. It’s not a minor contribution: deep sleep is one of the body’s primary windows for this kind of biological maintenance. A toddler who consistently falls short on sleep is missing out on the conditions that support healthy growth.
The 12-Month Sleep Regression
If your 1-year-old was sleeping well and suddenly isn’t, you’re likely dealing with the 12-month sleep regression. This is one of the more common disruptions parents face, and it has several overlapping causes: physical restlessness from increased mobility (many babies are pulling up or starting to walk), separation anxiety that peaks as social awareness develops, teething pain, or simply adjusting to new sleep patterns.
The signs are hard to miss. Your child may wake more frequently at night, resist bedtime with crying or fussiness, take longer to settle back down after waking, or suddenly start taking longer daytime naps. The good news is that this regression typically resolves within a few weeks. Keeping your bedtime routine consistent during this stretch, rather than introducing new sleep habits, tends to produce the smoothest recovery.
Signs Your Toddler Is Ready for One Nap
Somewhere between 12 and 18 months, most toddlers drop from two naps to one. At 12 months, the majority aren’t quite ready yet, but some early signs start appearing. Watch for these patterns:
- Fighting the second nap for more than 20 minutes on most days
- Refusing a nap entirely on a regular basis
- Waking earlier in the morning than usual
- Overnight sleep dropping below 10 hours
- Both naps shrinking to under an hour each
- Frequent overnight wakings that weren’t happening before
If you’re seeing one or more of these signs three to five days per week for about two weeks, your child is probably ready to transition. Rushing the switch before then often backfires, creating an overtired toddler who sleeps worse overall.
Night Feeds and Sleep at 12 Months
By 12 months, most children are getting enough calories during the day to support their growth and development without nighttime feeds. If your child is still waking to eat overnight, it’s often habit rather than hunger driving those wake-ups. When parents phase out night feeds, they commonly notice their child eats a bit more during the day to compensate, which is a normal and healthy adjustment.
Dropping night feeds doesn’t guarantee uninterrupted sleep on its own, but it does remove one of the most common reasons toddlers continue cycling through partial awakenings instead of learning to connect sleep cycles independently.
How Daytime Activity Affects Sleep
What your toddler does while awake has a measurable effect on how well they sleep. Research on children under five found that higher levels of physical activity in toddlers were associated with longer total sleep, better sleep quality, and more stable sleep patterns. Outdoor play specifically was linked to fewer night wakings, shorter time to fall asleep, and earlier bedtimes.
This doesn’t mean exhausting your child leads to better sleep. Overstimulation, especially close to bedtime, can have the opposite effect. The sweet spot is plenty of active, physical play earlier in the day, with a calmer wind-down period in the hour or so before bed. Even something as simple as more time crawling, walking, or playing outside during the morning can shift the quality of that night’s sleep.
