12 Month Sleep Schedule Guidelines
What's New at 12 Months (48-52 Weeks)?
Wake windows expand to 3-4 hours. This is a significant milestone that enables more flexible daily routines and activities.
Most 12 month olds can sleep 10-12 hour stretches without feeds. Many sleep fully through the night, though some still wake once.
At 12 months, babies have the developmental capacity for sleep training. This is a commonly recommended age to begin gentle independent sleep skill building.
While most 12-month-olds still need 2 naps, the transition to 1 nap typically happens between 13-18 months. Watch for signs in the coming months.
Congratulations! At one year, your toddler can eat what the family eats (safely prepared). You can also begin introducing whole cow's milk.
Object permanence develops around 12 months, leading to increased separation awareness. This may affect sleep as babies become more aware of parent absence.

Why Use Wake Windows Instead of a Fixed Schedule?
At 12 months, while babies have much more predictable sleep patterns than younger infants, daily wake times may still vary by 15-30 minutes based on hunger, development, and individual differences.
Wake windows (the time your baby stays awake between sleeps) remain valuable at 12 months because they provide flexibility while maintaining structure. Rather than watching the clock strictly, you observe how long your baby has been awake and respond to their sleep cues.
Wake Windows at 12 Months
At 12 months, typical wake windows are 3-4 hours. The first wake window may be 3 hours, and windows gradually extend through the day, with the last wake window (before bedtime) potentially reaching 3.5-4 hours.
By now, you may notice your baby settling into more predictable clock-based times naturally. Some families find a hybrid approach works best: loosely clock-based with flexibility around wake windows.
Bottom line: At 12 months, wake windows remain a useful tool, though many families transition toward clock-based schedules around this time. Use whichever method works best for your family's rhythm.

What's Normal at 12 Months
You can reliably predict bedtime, wake time, and nap times within a 15-30 minute window. Many babies naturally consolidate to more consistent schedules at this age.
While most 12-month-olds still need two naps, you may see signs of the 2-to-1 transition approaching (usually happens 13-15 months). Total daytime sleep: 2-3 hours.
By 12 months, most babies are nutritionally capable of sleeping 10-12 hours without feeding. Some sleep through, others still wake once. Both are normal. Night weaning may now be medically safe, depending on your baby's growth.
Around 12 months, babies develop object permanence and become aware of separation. This developmental leap may cause difficulty with bedtime or increased night wakings. This is temporary and developmentally normal.
At 12 months, toddlers can eat most family foods (cut appropriately) and transition from formula to whole milk. Three meals plus 2 snacks provide the majority of nutrition. This dietary shift supports sleep independence.
At 12 months, babies have the cognitive capacity to learn independent sleep skills. Gentle sleep training methods may be appropriate after consulting your pediatrician.
Remember: Every baby is different. These are averages. If your 12 month old still takes 3 naps, wakes once at night, or needs longer wake windows, that may still be normal. Trust your instincts and consult your pediatrician if concerned.
Wake Windows Guide: 12 Month Old (48-52 Weeks)
Age-Specific Wake Windows
First wake window (morning): 3-3.5 hours (often shortest)
Second wake window (midday): 3.5-4 hours
Last wake window (before bed): 3.5-4 hours (often longest)
Sleep Cues to Watch For
Early Signs (Sleepy Window)
- •Quieting down, less vocalizing
- •Staring blankly or losing interest in toys
- •Rubbing eyes or face
- •Yawning (1-2 yawns)
- •Turning away from interaction
- •Slowed movements, less active play
Late Signs (Overtired)
- •Crying or fussing
- •Arching back or body tension
- •Hyperactivity or "second wind" energy
- •Extreme clinginess
- •Difficult to calm or soothe
- •Fighting sleep intensely
At 12 months, try putting baby down early in the sleep cue window (when you see the first signs) rather than waiting for overtiredness. This often results in easier sleep onset and better sleep quality.
Sample Daily Schedules: 12 Month Old
Important: These are samples based on a 7:00 AM wake-up. Times will shift based on actual wake times. Some 12 month olds are still on 3 naps, while others have transitioned to 2 naps. Both are normal at this age.
Sample Schedule: 3 Naps (Not Appropriate for 12 Months)
| Time | Activity | Duration/Notes |
|---|---|---|
| 7:00 AM | Wake + Feed | Breast/bottle feed, diaper change |
| 7:15-9:15 AM | Awake Time | Play, activity, tummy time (2h WW) |
| 9:15-10:30 AM | Nap 1 | First nap: 1-1.5 hours |
| 10:30 AM | Feed | Feed upon waking |
| 10:45 AM-12:45 PM | Awake Time | Outdoor time, activities, solids (if started) (2h WW) |
| 12:45-2:15 PM | Nap 2 | Longest nap: 1.5-2 hours |
| 2:15 PM | Feed | Feed upon waking |
| 2:30-4:30 PM | Awake Time | Play, social time, activities (2h WW) |
| 4:30-5:15 PM | Nap 3 | Short afternoon nap: 45-60 min |
| 5:15 PM | Feed | Feed upon waking |
| 5:30-7:00 PM | Awake Time | Family time, calm activities (1.5h WW) |
| 7:00-7:30 PM | Bedtime Routine | Bath, massage, pajamas, feed, book, cuddles |
| 7:30 PM | Bedtime | Down for the night |
| 7:30 PM - 7:00 AM | Nighttime Sleep | Many sleep through; some wake once. 9-12 hour stretch typical. |
Sample Schedule: 2 Naps (Standard for 12 Months)
| Time | Activity | Duration/Notes |
|---|---|---|
| 7:00 AM | Wake + Feed | Breast/bottle feed, diaper change |
| 7:15-9:15 AM | Awake Time | Play, activity, solids (2h WW) |
| 9:15-10:45 AM | Nap 1 | First nap: 1.5-2 hours |
| 10:45 AM | Feed | Feed upon waking |
| 11:00 AM-1:30 PM | Awake Time | Outdoor activities, social time, play (2.5h WW) |
| 1:30-3:15 PM | Nap 2 | Afternoon nap: 1.5-2 hours |
| 3:15 PM | Feed | Feed upon waking |
| 3:30-7:00 PM | Awake Time | Family activities, snack/solids, calm time (3.5h WW) |
| 7:00-7:30 PM | Bedtime Routine | Bath, massage, pajamas, feed, book, cuddles |
| 7:30 PM | Bedtime | Down for the night |
| 7:30 PM - 7:00 AM | Nighttime Sleep | Many babies sleep 10-12 hours without feeds at this age. |
Schedule Note: The last nap should ideally end by 4:00-4:30 PM (if on 3 naps) or by 3:15 PM (if on 2 naps) to protect bedtime between 7:00-8:00 PM. This prevents overtiredness and bedtime resistance.
How many naps should a 12 month old take?
At 12 months, most toddlers should be taking 2 naps per day, though some may start fighting one.
- Morning nap: Usually 1-1.5 hours, around 9:00-10:00 AM
- Afternoon nap: Usually 1-2 hours, around 1:00-2:00 PM
- Total daytime sleep: 2.5-3.5 hours across naps
Remember: At 12 months, your baby should be firmly on 2 naps. Nap resistance is common due to developmental leaps (walking, first words) but doesn't mean they're ready for 1 nap. Most toddlers don't transition to 1 nap until 14-18 months.
How long should a 12 month old nap?
At 12 months, nap durations may vary depending on whether baby is still on 3 naps or transitioning to 2 naps:
Morning nap: 1-1.5 hours | Midday nap: 1.5-2 hours | Afternoon nap: 45-60 min | Total: 3-4 hours
Morning nap: 1.5-2 hours | Afternoon nap: 1.5-2 hours | Total: 3-4 hours
Note: Some 12 month olds still have 30-45 minute naps (one sleep cycle). If your baby is sleeping this short and seems well-rested, it may be sufficient. Longer naps typically develop over time.
When should the last nap be for a 12 month old?
Last nap timing significantly impacts bedtime success at 12 months:
Last nap should end by 4:00-4:30 PM maximum. This provides 2.5-3 hours of awake time before bedtime at 7:00-8:00 PM. If the last nap ends later, bedtime may shift later.
Last nap should end by 3:00-3:30 PM to allow 3.5-4 hours awake before bedtime. This longer wake window helps consolidate nighttime sleep.
Pro Tip: If you're experiencing bedtime resistance, check when the last nap ended. If it's too late, baby may not be tired enough (or conversely, may be overtired). Adjusting last nap timing often helps.
When is bedtime for a 12 month old?
Most 12 month olds have a bedtime between 7:00 PM and 8:00 PM. Here's what works well:
- Early bedtime (7:00 PM): Supports longer nighttime sleep. Good if baby wakes early (before 7:00 AM) or you prefer earlier mornings.
- Mid-range bedtime (7:30 PM): Works well for many families. Balances early wake and morning routines.
- Later bedtime (8:00 PM): Suits families with later schedules or if baby naturally wakes later (7:30-8:00 AM).
Key: Consistency matters most. Aim for the same bedtime within a 15-30 minute window every night. This supports healthy circadian rhythm development and often improves sleep quality and duration.
Looking Ahead: The 2-to-1 Nap Transition
Not quite there yet!
At 12 months, you might hear about toddlers dropping to one nap. While some are ready, most 12-month-olds still benefit greatly from two naps. Moving to one nap too early can cause significant sleep regression. The 3-to-2 transition is ancient history for you now; the focus is maintaining a restful 2-nap rhythm until 13-15 months.
Signs Your Baby May Be Ready to Transition:
- Baby starts refusing the afternoon nap consistently
- The day goes more smoothly with just 2 naps
- Baby sleeps better at night when the afternoon nap is shortened or skipped
- Wake windows are now consistently 2.5+ hours
- Baby seems to have enough energy for a longer afternoon wake time
How to Transition: Step-by-Step
Observe for 1-2 weeks. Is baby consistently fighting the afternoon nap or taking forever to fall asleep? Is bedtime becoming a struggle due to a late second nap?
Start by skipping it some days. If baby transitions smoothly, continue skipping. If baby becomes overtired, keep the nap for a few more weeks.
With 2 naps, wake windows may extend. The last wake window (afternoon) will be 3-4 hours. Bedtime may need to shift earlier initially.
The transition can take 2-4 weeks as your baby's body adjusts to longer wake windows. Sleep may be disrupted temporarily.
Important Reminders:
- • Don't force the transition too early. If baby still needs 3 naps at 12 months, that's completely normal.
- • If the 2-nap schedule isn't working (increased night wakings, very early wake times), go back to 3 naps for a few more weeks.
- • The transition can happen gradually over several weeks or suddenly over a few days—both are normal.
- • Some babies transition to 2 naps by 5 months; others don't until 8-12 months. There's no "right" timeline.
Developmental Milestones at 12 Months
By 12 months, many babies can stand without support for several seconds or longer, marking a major motor development milestone as they approach walking.
Some one-year-olds take their first independent steps, while others walk while holding hands or pushing furniture. Walking typically begins between 9-15 months.
Babies develop the ability to lower themselves from standing to sitting position without assistance, showing improved balance and coordination.
Fine motor skills advance as babies learn to turn pages in board books, showing interest in reading and visual stimulation.
Language comprehension develops significantly. Babies respond consistently to their name and can follow simple one-step directions like "come here" or "give me."
A regression often occurs around the first birthday due to new walking skills, developmental transitions, and sometimes teething or illness. Maintaining consistency helps navigate this phase.
Sleep Impact: These developmental leaps—especially separation anxiety and potentially teething—may temporarily disrupt sleep. This is temporary and normal. Maintaining consistent routines may help during transitions.
Activities for 12 Month Olds
At 12 months, babies are more interactive and can enjoy a wider variety of activities. These activities may help with daytime stimulation and better sleep:
Physical Activities
- • Stacking activities (blocks, cups)
- • Busy board exploration
- • Role-playing with household items
- • Walking practice (with assistance)
- • Making music together
Sensory Activities
- • Exploring textures and materials
- • Water play (bath time)
- • Listening to music and sounds
- • Looking at high-contrast images
- • Feeling different fabrics
Social Activities
- • Peek-a-boo games
- • Singing and talking
- • Interaction with caregivers
- • Playgroups (short visits)
- • Mirror play (seeing their face)
Outdoor Activities
- • Nature exploration
- • Walks in stroller or carrier
- • Fresh air and sunlight exposure
- • Observing plants and animals
- • Safe outdoor exploration
Tip: Adequate daytime activity and stimulation supports better daytime sleep and nighttime sleep. But avoid overstimulation near bedtime. Wind down activities 1-2 hours before sleep.
Bedtime Routine for 12 Month Olds
A consistent bedtime routine signals to your baby that sleep is coming. This may help with separation anxiety and sleep independence. A typical 30-45 minute routine might look like:
5:45-6:00 PM (Pre-bedtime wind-down)
Dim lights, move to quiet area, slow down activities. Start moving toward bedroom.
6:00-6:15 PM (Bath time)
Warm (not hot) bath with gentle play. This soothes and signals bedtime. Can include infant massage after.
6:15-6:25 PM (Pajamas and feeding)
Change into clean diaper and pajamas. Feed (breast or bottle) in a calm, dim room. This is often the last food before sleep.
6:25-6:35 PM (Quiet time/reading)
Read a board book, sing soft songs, cuddle. Keep it boring and calm—the goal is wind-down, not entertainment.
6:35-7:00 PM (To bed)
Dim/turn off lights. Place baby in crib drowsy but awake (ideally). Say goodnight. Leave. Use a consistent exit phrase.
Bedtime Routine Tips:
- • Keep it 30-45 minutes long, starting 45 min before target sleep time
- • Use the same sequence every night (babies love predictability)
- • Dim or turn off lights during the routine
- • Keep the room cool (around 68-72°F is ideal)
- • Use white noise if your home is noisy
- • Avoid screens 1-2 hours before bedtime
- • Consider a sleepsack instead of loose blankets for safety
- • If using a pacifier, introduce it in the routine
Should I still swaddle my 12 month old?
No—by 12 months, swaddling should be stopped. Here's why:
Most 12 month olds roll both ways. A swaddled baby who rolls onto their stomach cannot roll back, creating a safety risk.
The American Academy of Pediatrics recommends stopping swaddling when babies show signs of rolling (usually by 4-5 months, certainly by 12 months).
Safe alternatives at 12 months:
- Sleep sacks/wearable blankets: Keep baby warm without loose blankets or swaddling
- Lightweight sleepers: Footie pajamas provide warmth
- Crib setup: Firm mattress, fitted sheet, no pillows, blankets, or bumpers
Note: If your baby has been swaddled and is now rolling, transition out gradually. Some babies sleep poorly for a few nights without swaddling, then adjust. This is temporary.
What if my 12 month old needs the pacifier to sleep?
It's common for 12 month olds to rely on pacifiers for sleep. Here are your options:
Using a pacifier at sleep is fine. The AAP recommends pacifiers for the first year as they may reduce SIDS risk. At 12 months, there's no need to wean yet.
If baby wakes because the pacifier fell out, you may need to replace it multiple times. Some families use the "disappearing pacifier" method (leaving multiple pacifiers in the crib so baby can find them).
Pacifier weaning is often easier closer to 2-3 years old. Weaning too early (at 12 months) may increase night wakings. Consider waiting until after 12 months.
Sleep Training Consideration: If you're planning to sleep train, having baby independent of the pacifier may help. But it's not required. Many families sleep train with pacifier use.
Can a 12 month old sleep through the night?
Yes—many 12 month olds can sleep through the night (10-12 hours) without feeds. Here's what you need to know:
By 12 months, most babies (especially those eating solids) can meet their nutrition needs during the day and don't medically need night feeds. But some babies may still wake.
Some 12 month olds sleep 10-12 hours without waking. Others wake once. Both are normal. Growth, individual metabolism, and hunger all play roles.
Night weaning (stopping night feeds) may be appropriate at 12 months with your pediatrician's agreement. But it's not necessary or required.
Check with Your Pediatrician: Before night weaning, confirm your baby is growing well and has been cleared to sleep without feeds. Some babies still need night nutrition.
Why is my 12 month old fighting sleep?
There are several reasons a 12 month old may fight sleep:
Developmental Reasons
- • Separation anxiety (object permanence)
- • Teething discomfort
- • Developmental leaps/mental growth
- • Increased awareness of surroundings
Sleep Schedule Reasons
- • Wake windows too long
- • Wake windows too short (undertired)
- • Last nap too late in the day
- • Too much stimulation before bed
Environmental Reasons
- • Room too warm or cold
- • Not dark enough
- • Noise disturbances
- • Uncomfortable sleep surface
Physical Reasons
- • Hunger or needing solids
- • Discomfort (gas, reflux)
- • Illness or ear infection
- • Diaper issues
What to Do: Check the most obvious causes first (wake windows, last nap timing, room temperature, hunger). If fighting sleep is sudden or severe, contact your pediatrician to rule out illness.
Why are my 12 month old naps suddenly short?
Short naps (30-45 minutes) can happen at 12 months for several reasons:
30-45 minutes is one complete sleep cycle. Some 12 month olds cannot connect sleep cycles independently yet. Longer naps develop over time.
If wake windows are 2.5-3+ hours but baby is transitioning, they may be overtired, leading to short, poor-quality naps.
At 12 months, separation anxiety may wake baby after one cycle. Hearing you nearby may trigger waking.
Developmental growth spurts can temporarily disrupt sleep. Naps typically return to normal after the leap passes.
Noise, temperature changes, or discomfort may wake baby after one cycle.
When Short Naps Are OK: If your baby seems happy and well-rested after 30-45 min naps, it may be sufficient. Not all babies need 2-hour naps. However, if baby seems tired or fussy after short naps, longer naps are beneficial.
How do I handle early morning wakings with my 12 month old?
Early morning wakings (before 6:00 AM) are common at 12 months. Here's how to address them:
If baby wakes before 6:00 AM, they may actually be overtired. Try moving bedtime 15-30 minutes earlier for a few days. Earlier bedtime may improve early wake times.
If the last nap ends too late, night sleep may be disrupted. Ensure last nap ends by 4:00-4:30 PM (3-nap schedule) or 3:15 PM (2-nap schedule).
If wake is before your target wake time, try keeping baby in crib (if safe) for 15-20 more minutes to see if they resettles. If they're awake and happy, this teaches them to self-entertain.
Ensure baby is not hungry, too hot/cold, or uncomfortable. Early wakings can sometimes indicate need for more daytime calories.
Note: Some variation in wake time is normal. A 6:00-7:00 AM window is still considered normal wake time. Perfect consistency comes later.
Safe Sleep Guidelines for 12 Month Olds
AAP Safe Sleep Recommendations (updated):
Firm, flat surface (crib, bassinet, or play yard that meets safety standards). Crib rails should be 2-3 inches apart.
Fitted sheet only. NO pillows, blankets, bumpers, or stuffed animals. All increase SIDS and suffocation risk.
Use sleep sacks instead of blankets. Appropriate weight for room temperature (tog rating).
AAP recommends room-sharing (baby's sleep space in your room) for at least the first 12 months, ideally the first year. This reduces SIDS risk.
Pacifier at nap and bedtime may reduce SIDS risk. No need to introduce if baby doesn't want one.
Keep room cool (68-72°F). Overheating increases SIDS risk.
Avoid wedges, positioners, sleep pods, and "co-sleepers" that attach to bed. These lack safety evidence.
Baby should be placed on back for naps and bedtime. If baby rolls to stomach on their own (which is common at 12 months), it's OK to leave them.
Avoiding Common Unsafe Practices:
- • Do NOT use sleep sacs that zip around the neck (strangulation risk)
- • Do NOT sleep in the same bed as baby (co-sleeping increases SIDS risk)
- • Do NOT use sleep props that haven't been safety tested
- • Do NOT overdress—overheating increases SIDS risk
- • Do NOT use crib bumpers or padding (suffocation risk)
SIDS Awareness: SIDS (Sudden Infant Death Syndrome) peak is 1-4 months, but occurs through the first year. Safe sleep practices reduce risk significantly.
Sleep Training at 12 Months: Is It Appropriate?
Yes—12 Months is a Developmentally Appropriate Age for Sleep Training
At 12 months, babies have the cognitive capacity to learn to fall asleep independently. Sleep training at this age is widely considered safe and appropriate by pediatric sleep experts and the American Academy of Pediatrics (with pediatrician clearance).
Gentle Sleep Training Methods for 12 Months:
Place baby in crib when drowsy but not fully asleep. Gradually increase the level of awakeness at placement. Gentlest method.
Put baby in crib and pat/soothe while they fall asleep. Gradually reduce contact over days/weeks. Allows touch while encouraging independence.
Put baby in crib and leave without intervention. Baby learns to self-soothe. Works quickly but may be emotionally difficult for some parents.
Put baby in crib and allow brief crying before checking. Gradually extend time between check-ins. Middle ground between gentler and full extinction methods.
Sit by crib but don't touch. Gradually move chair toward door over weeks. Very gradual, gentle approach.
Before Starting Sleep Training at 12 Months:
- ✓ Consult your pediatrician to ensure baby is healthy
- ✓ Confirm baby is ready (rule out hunger, illness, developmental leaps)
- ✓ Ensure wake windows are age-appropriate
- ✓ Establish a solid bedtime routine first
- ✓ Choose a method you can consistently implement
- ✓ Ensure both parents are on the same page
- ✓ Be prepared for 3-7 nights of potential difficulty before improvement
Important: Sleep training works best when baby is well-fed, healthy, not in a developmental leap, and when both parents are ready and consistent. Success depends on implementation and timing.
Feeding Schedule for 12 Month Olds
Breast and Formula Feeding:
Most 12 month olds feed every 2.5-3.5 hours during the day. With a 3-nap schedule, this typically means 4-5 feeds per day. With a 2-nap schedule, this may be 4-5 feeds.
Breastfed: Baby typically nurses 5-8 min per side, 5-6 times per day. Formula-fed: Typically 6-8 oz per bottle, 4-5 bottles per day. Every baby is different.
Many 12 month olds no longer need night feeds nutritionally, but some babies wake and eat anyway. Feeding 0-1 times per night is typical.
Toddler Nutrition: Transitioning to Family Meals
At one year, your baby can eat what you eat (with safety modifications like cutting grapes). Eat together to model healthy habits.
You may transition from formula/breastmilk to whole cow's milk (or fortified alternative). Limit to 16-20oz per day to save appetite for food.
Honey is now safe! You can also be a bit more liberal with seasonings, though keep salt moderate.
Pediatric dentists recommend weaning off bottles around 12 months to protect teeth. Transition fully to straw or open cups.
Sample Daily Feeding Schedule (2-Nap Schedule):
7:00 AM: Wake + Breakfast (Solids + Milk in cup)
9:30-11:00 AM: Nap 1
11:00 AM: Snack
12:30 PM: Lunch (Solids + Milk/Water)
2:00-3:30 PM: Nap 2
3:30 PM: Snack
5:30 PM: Dinner (Family Meal)
6:30 PM: Bedtime routine (Book, Cuddles)
Consult Your Pediatrician: Every baby's feeding needs are different. Your pediatrician can confirm your baby is getting adequate nutrition and growing well. Don't compare feeding amounts to other babies.
