How Much Sleep Does A One-Year-Old Need? | Hours Chart

Parents ask this a lot because year one is a big shift. Your toddler is busier, naps are changing, and bedtime can wobble. The research sets a clear range for healthy totals. Day to day, you’ll shape those hours into a simple routine that fits meals, play, and family life.

How Much Sleep Does A One-Year-Old Need? Practical Targets

The science-based target for ages 1–2 is 11–14 hours in 24 hours, counting naps. Many toddlers land near 12–13 hours. Night sleep tends to carry most of the load, with one long nap or two shorter naps filling the rest.

One-Year-Old Sleep At A Glance (Early Cheat Sheet)

Use this table as a quick reference while you set your routine.

Sleep Component	Target Hours	Notes
Total In 24 Hours	11–14	Includes night sleep and naps
Night Sleep	10–12	Most families aim for a steady bedtime and wake time
Daytime Naps (Total)	1.5–3	One long nap or two shorter naps
Naps Per Day	1–2	Many shift to one nap between 12–18 months
Nap Length (Each)	45–120 min	Longer single nap once on a one-nap schedule
Bedtime Window	6:30–8:30 pm	Pick a window your toddler can meet most nights
Night Wakings	0–2 brief	Short wakings are common and often self-settle
Morning Rise Time	6:00–7:30 am	Keep it steady to anchor the whole day

Why The Range Matters

Some toddlers thrive at the high end of the range; others run lower and stay cheerful and alert. Watch daytime mood, attention during play, and late-day crankiness. If those look steady and growth checks stay on track, your total is likely in a good spot.

How Much Sleep A One-Year-Old Needs By Schedule

Here are two sample days that hit the 11–14 hour target from different angles. Use them as templates, then tweak durations and clock times to suit meals, daycare, and family rhythms.

Sample One-Nap Day (Common After 14–18 Months)

• 7:00 am: Wake
• 12:15–2:00 pm: Nap (1 hr 45 min)
• 7:30 pm: Bedtime

Tally: ~10 hr 30 min at night + 1 hr 45 min nap ≈ 12 hr 15 min in 24 hours.

Sample Two-Nap Day (Common Right At 12 Months)

• 6:45 am: Wake
• 9:45–10:30 am: Nap 1 (45 min)
• 2:00–3:30 pm: Nap 2 (90 min)
• 7:15 pm: Bedtime

Tally: ~10 hr 45 min at night + 2 hr 15 min naps ≈ 13 hr in 24 hours.

When To Drop From Two Naps To One

Clues include short or skipped second naps, long bedtime battles, long late-night parties, or pre-dawn wakeups. Shift toward one nap by stretching morning play a bit at a time and protecting an early bedtime during the change.

Bedtime, Wake Windows, And Cues

At this age, fixed clock times help more than chasing a moving “window.” Build a steady rhythm: morning wake, active play, daylight time, mealtimes that don’t drift too late, and a simple pre-sleep routine. Keep the room dark and quiet at night, and dim and calm before naps. A cool, comfy room supports solid sleep.

Build A Simple, Repeatable Routine

Pick 3–5 steps you can run on autopilot: bath, pajamas, feed, brush, story, lights out. Keep it short so bedtime doesn’t slide. On rough nights, stay calm, keep steps the same, and end at the usual time. Repetition is what teaches the cue.

Protect The Nap To Save Bedtime

Long late-day naps push bedtime out. Aim to end daytime sleep at least three hours before lights out. If daycare runs late naps, slide bedtime a touch later and pull it back a few nights later.

What The Research Says

Two respected bodies anchor the target range. The American Academy of Sleep Medicine puts toddlers at 11–14 hours in 24 hours and the pediatric academy backs those numbers. Public-health guidance lines up with that range as well. You can link the rule right in your notes so caregivers and relatives see the same target.

Feeding, Screens, And Movement

Time Meals To Help Sleep

Big, late dinners can stall bedtime. Front-load calories earlier, keep a light snack in the evening, and brush before stories. Milk is fine near bedtime if teeth get cleaned after.

Daylight And Active Play

Outside time sets the body clock. Short walks and park time burn energy and prime the next sleep period. Aim for daylight before noon and again in the afternoon.

Screens And Late Evenings

Bright screens near bedtime make it harder to wind down. Shut them off 60–90 minutes before lights out and swap in quiet play or books.

Troubleshooting Common Sleep Snags

Year one comes with changes: separation blues, teeth coming in, growth spurts, colds. Most bumps pass with steady routines and a little schedule support.

Common Issue	Likely Causes	What To Try
Early Morning Wakeups	Late bedtime, room light, dawn birds	Shift bedtime slightly earlier, blackout shades, white noise
Bedtime Battles	Overtired child, naps too late, long wind-downs	Protect nap timing, tighten routine to 20–30 minutes
Short Naps	Sleep pressure too low, noisy room	Stretch wake time by 10–15 minutes, darken the room
Split Nights	Too much day sleep, late second nap	Trim nap minutes, end naps earlier in the day
Nap Refusal At Daycare	New setting, stimulation, light	Send a comfort item if allowed, ask for a darker spot
Frequent Night Wakings	Overtiredness, habits from illness, teeth	Guard bedtime, keep responses brief and calm, reset once well
Late Bedtime Creep	Sliding naps, weekend drift	Anchor wake time; nudge bedtime earlier by 10–15 minutes nightly

Teething, Illness, And Regressions

Teething can tighten the window for sleep. Pain relief approved by your clinician can help. During illness, keep the routine but lower expectations. Once your child feels better, return to your usual timing within a few days so the pattern doesn’t reset around night care.

Travel And Time Changes

For short trips, protect the nap and keep bedtime steps the same. For longer trips, shift the schedule in small moves over a few days. Bring familiar sleep gear so the new room feels safe: the same sleep sack, the same story, the same sound machine settings.

Room Setup That Helps

• Darkness: Block street light and dawn glow.
• Sound: Steady white noise can mask bumps and chatter.
• Temperature: A cool room supports longer stretches.
• Safe Space: Crib free of loose items; firm mattress, fitted sheet.

Daycare And Caregiver Handoffs

Share the target range and the plan in plain numbers: total hours, nap count, nap cut-off time, bedtime window. Note any comfort items or wind-down steps that soothe your child. Small differences between home and daycare are normal. Keep your home schedule steady, and your toddler will adapt.

Red Flags That Warrant A Check-In

Reach out to your pediatrician if you see loud snoring with gasps, long breathing pauses, night sweats without fever, very short sleep despite steady routines, or a sudden drop in daytime energy. If growth or development checks raise concerns, ask how sleep might fit into the plan.

How Much Sleep Does A One-Year-Old Need? The Bottom Line

Stick to the 11–14 hour daily range, favor a steady bedtime, and keep naps early enough to protect the night. When life throws a curve—teeth, colds, trips—get through it, then slide back to your base plan. That mix of clear targets and flexible days is what keeps the whole house rested.

Finally, write the target right on your fridge: “11–14 hours total; 1–2 naps; bedtime steady.” Share it with grandparents and sitters so the same plan runs no matter who’s in charge.
