One-year-olds need 11 to 14 hours of total sleep per 24-hour period, including naps. Most of that sleep happens at night, with the remainder split across one or two daytime naps. Where your child falls in that range depends on their individual needs, but consistently landing below 11 hours is a sign something may need adjusting.
How That Sleep Typically Breaks Down
At 12 months, most toddlers sleep roughly 10 to 12 hours overnight and get the remaining 2 to 3 hours from daytime naps. Some one-year-olds still take two naps a day (usually a morning nap and an afternoon nap), while others are beginning to consolidate into a single longer nap. Neither pattern is wrong. The total amount across the full day matters more than how it’s divided.
Between naps and overnight stretches, a 12-month-old can typically handle about 3 to 4 hours of awake time before needing sleep again. These “wake windows” are useful for planning your day. If your child wakes at 7 a.m. and takes two naps, the first nap usually falls around 10 or 10:30, with the second around 2 or 2:30 p.m. Bedtime for most one-year-olds lands somewhere between 7 and 8 p.m.
The Two-Nap to One-Nap Transition
Most toddlers drop from two naps to one between 18 and 24 months, not right at 12 months. If your one-year-old is still happily taking two naps, there’s no reason to rush the change. Signs that a child is ready to transition include consistently fighting one of the naps, taking a long time to fall asleep at the usual nap time, or having their second nap push so late that it interferes with bedtime.
The transition itself is often messy. For a few weeks, your child might need two naps on some days and one on others. On single-nap days, moving bedtime 30 minutes earlier can help bridge the gap until they adjust. Once the transition is complete, the single nap usually falls after lunch and lasts 1.5 to 3 hours.
Why Sleep Falls Apart Around 12 Months
Right around their first birthday, many toddlers hit a sleep regression. A child who had been sleeping well suddenly starts waking at night, resisting naps, or taking forever to fall asleep. This is one of the most common regressions parents notice, and it’s driven by a burst of developmental activity. Learning to walk, increased awareness of their surroundings, and early language development all fire up a one-year-old’s brain in ways that make settling down harder.
Sleep regressions are temporary, though they don’t always feel that way in the moment. Most resolve within a few weeks as the child adjusts to their new skills. The most helpful thing you can do is stay consistent with your existing sleep routines rather than introducing new habits (like rocking to sleep or bringing the child into your bed) that may be harder to undo later.
Signs Your One-Year-Old Isn’t Getting Enough
Toddlers who are chronically short on sleep don’t always look sleepy. In fact, they often look the opposite. An overtired one-year-old may become hyperactive, clingy, or unusually fussy. Frequent meltdowns over small things, difficulty focusing during play, and increased clumsiness are all common signals. Some overtired toddlers paradoxically fight sleep even harder, creating a cycle that’s tough to break.
If your child is consistently sleeping fewer than 11 hours in a 24-hour period and showing these behaviors, it’s worth looking at the schedule. A bedtime that’s too late, nap timing that’s off, or wake windows that stretch too long are the most common culprits.
Setting Up a Safe Sleep Space
At 12 months, safe sleep guidelines still apply. The safest crib is a bare crib: firm mattress, fitted sheet, nothing else. Pillows, blankets, quilts, bumper pads, and stuffed animals all remain hazards for toddlers in cribs. The AAP recommends avoiding soft bedding because of the risk of suffocation. If you’re worried about your child being cold, a wearable sleep sack is a safer alternative to a loose blanket.
Room-sharing (your child sleeping in your room but in their own crib) is still considered protective at this age, though many families have already moved the crib to a separate room by 12 months. If your child sleeps in their own room, a baby monitor can provide peace of mind without the disruptions that come from being in the same space.
Building a Bedtime Routine That Works
One-year-olds thrive on predictability. A short, consistent bedtime routine signals to their brain that sleep is coming. This doesn’t need to be elaborate. A bath, a book, a song, and into the crib works for most families. The key is doing it in the same order at roughly the same time each night. Fifteen to 30 minutes is plenty.
Timing matters as much as the routine itself. Putting a one-year-old down when they’re drowsy but still awake helps them learn to fall asleep independently, which also means they’re more likely to put themselves back to sleep after normal nighttime wakings. Every child wakes briefly several times a night. The ones who “sleep through” are simply the ones who know how to drift back off without help.
