Babies need around 11 to 17 hours of sleep per day, with total hours gently dropping as age, feeding habits, and development change.
Baby sleep can feel like a moving target. One month your newborn naps around the clock, and a few months later you are trying to stretch wake windows and protect bedtime. Charts help, yet every family also lives in the real world with feeds, colds, growth spurts, and life schedules. This guide walks through how much sleep babies need by age, what healthy ranges look like, and how to use those ranges without stressing over every nap.
How Much Sleep Do Babies Need By Age? Age-By-Age Snapshot
Sleep needs shift a lot in the first years. The numbers in this chart draw from large pediatric sleep recommendations and line up with what many parents see at home. The ranges include naps and night sleep over a full 24-hour day.
| Age Range | Total Sleep In 24 Hours | Typical Day/Night Split |
|---|---|---|
| Newborn (0–3 months) | 14–17 hours | Day and night mixed, 8–9 hours at night in short stretches |
| Young Infant (4–6 months) | 12–16 hours | 9–10 hours at night, 3–5 hours across 3–4 naps |
| Older Infant (7–11 months) | 12–15 hours | 10–11 hours at night, 2.5–4 hours across 2–3 naps |
| One-Year-Old (12–17 months) | 11–14 hours | 10–11 hours at night, 1.5–3 hours across 1–2 naps |
| Toddler (18–23 months) | 11–14 hours | 10–11 hours at night, 1–3 hours in one nap |
| Two-Year-Old (24–35 months) | 11–13 hours | 10–11 hours at night, 1–2 hours in one nap |
| Preschooler (3–4 years) | 10–13 hours | 10–12 hours at night, short or no nap |
These ranges line up with consensus guidelines from sleep medicine groups and public health agencies that group babies and toddlers by age and total hours of sleep across the day. The exact sweet spot for your child sits somewhere inside the band for each stage.
Baby Sleep By Age Chart And Daily Rhythms
Looking at numbers on a chart is one thing. Living through each stage with feeds, diaper changes, and growth spurts feels different. This section walks through what the sleep ranges above look like in daily life for each age group.
Newborn Sleep: 0–3 Months
Newborns often sleep 14–17 hours spread across day and night. Sleep comes in small chunks, usually 1–3 hours at a time. Many babies mix up days and nights, because the internal body clock has not settled yet.
At this age, feeds drive the schedule. Wake windows stay short, often 45–60 minutes from one sleep to the next. Plenty of contact naps, on-demand feeds, and motion sleep in a carrier or stroller are common. Safe positioning still matters, so aim to end every stretch of sleep on a flat, firm surface once your baby settles.
Young Infant Sleep: 4–6 Months
Around four months, sleep starts to organize. Babies in this stage often need 12–16 hours in 24 hours, with a longer stretch at night and three to four naps during the day. Many parents notice a “sleep regression” as the brain shifts into more mature sleep cycles.
Wake windows lengthen to around 1.5–2.5 hours. Bedtime lands earlier, often between 6:30 and 8:30 p.m. A simple, repeated wind-down routine, such as feed, short book, cuddle, and song, helps signal that night sleep is different from naps.
Older Infant Sleep: 7–11 Months
By the back half of the first year, many babies settle into 12–15 hours of sleep per day. Two solid naps are common, with some babies taking an extra short catnap on long days. Night sleep often stretches to 10–11 hours with fewer night feeds, though some babies still wake to eat.
Wake windows stretch toward 2.5–4 hours, and many families settle into a predictable rhythm: morning nap, afternoon nap, and early bedtime. Standing, crawling, and pulling up can stir up night wakings, since the brain practices new skills even at night.
Toddler Sleep: 12–23 Months
One-year-olds still need around 11–14 hours of sleep. Many hold onto two naps until 14–18 months, then merge into one longer midday nap. Bedtime routines gain more steps as toddlers add teeth brushing, toilet time, and favorite songs or stories.
Separation worries and big feelings can show up around this stage. Calm repetition helps. A short, predictable routine and a steady response to protests give toddlers a sense of safety without turning bedtime into a long back-and-forth.
Two- And Three-Year-Old Sleep
From two to three years, total sleep usually shifts down toward 11–13 hours. Many children nap once, often 1–2 hours after lunch, while some three-year-olds start skipping naps on some days. Bedtime may need to move earlier on no-nap days to prevent late-day meltdowns.
At this age, stalling becomes an art form. Extra water, one more book, and more calls from the bedroom are common. A calm “last chance” step built into the routine, such as one final drink and one short song, helps set limits while still feeling kind.
How Official Sleep Recommendations Fit Baby Life
Large expert groups have pulled together research on child health and sleep. The American Academy of Sleep Medicine sets age-based sleep duration ranges from infancy through the teen years, which many pediatric groups endorse. Those ranges match the hours listed in the first chart.
Public health agencies also share broad guidance on sleep needs across childhood. Pages such as the CDC’s about sleep page group babies, toddlers, and preschoolers by age and show how daily sleep recommendations change across growth stages. Charts in parenting books and apps usually draw from the same research base.
These official ranges give a strong starting point, yet they still leave room for your baby’s personality, health, feeding, and family routine. Two children the same age can sit at different spots inside the range and still be well rested.
Safe Sleep While You Work With Sleep By Age
Sleep length is only one piece of the picture. Safe sleep habits matter just as much. Pediatric groups advise placing babies on their backs for every sleep, using a firm, flat mattress with a fitted sheet, and keeping soft objects and loose blankets out of the sleep space.
The American Academy of Pediatrics safe sleep guidance, such as the summary on this safe sleep page, also recommends room-sharing without bed-sharing for at least the first six months. That setup helps with feeding and checking on your baby while lowering the risk of sleep-related accidents.
Safe sleep rules stay in place even as your baby’s age-based sleep needs shift. A three-month-old and a six-month-old might need different total hours, yet both still sleep on their backs in their own flat space.
Sample Daily Routines For Baby Sleep By Age
Sleep charts answer “how much,” but many parents also want to see “how does this fit into a day.” The sample days below match the ranges in the first table. They are not strict schedules, just templates you can tweak around feeds, childcare, and family life.
| Age | Daytime Pattern | Night Pattern |
|---|---|---|
| 2 months | Wake 7 a.m.; 4–5 naps of 45–90 minutes; awake 45–75 minutes between naps. | Bed 9–10 p.m.; 8–9 hours total with 2–3 feeds and short wake periods. |
| 5 months | Wake 7 a.m.; 3–4 naps totaling 3–4 hours; awake 1.5–2.5 hours between naps. | Bed 7–8 p.m.; 9–10 hours with 1–2 feeds; some brief self-settling. |
| 9 months | Wake 7 a.m.; 2–3 naps totaling 2.5–3.5 hours; awake 2.5–3.5 hours between naps. | Bed 7–8 p.m.; 10–11 hours; many babies wake once or sleep through. |
| 15 months | Wake 7 a.m.; one morning nap phase shifting to one midday nap of 1.5–2.5 hours. | Bed 7–8 p.m.; 10–11 hours; some brief wakings linked to teething or leaps. |
| 2 years | Wake 7 a.m.; one nap after lunch, often 1–2 hours; quiet time if nap is skipped. | Bed 7–8 p.m.; 10–11 hours; wakes linked to night fears or big changes. |
| 3 years | Wake 7 a.m.; short nap or rest time early afternoon; calm play late day. | Bed 7–8 p.m.; 10–12 hours; bedtime may shift slightly later on no-nap days. |
Use these patterns as a guide, not a strict timetable. Some babies lean earlier or later, some need longer naps, and some move through stages faster or slower. Many parents adjust wake time and bedtime first, then shape naps around those anchors.
How To Tell If Your Baby Gets Enough Sleep
Charts answer the question “how much sleep do babies need by age?” but your baby’s behavior during the day tells you even more. A well-rested baby usually wakes in a better mood, feeds with good focus, and shows steady energy during wake windows.
Signs of too little sleep include short naps paired with cranky wake periods, long late-day meltdowns, and early rising that does not improve with earlier bedtimes. On the flip side, a baby who sleeps far beyond the upper end of the chart for their age and seems low-energy when awake may need a check-in with a pediatrician.
Growth spurts, teething, illness, and travel all change sleep for a while. When life settles again, most babies drift back toward their usual pattern without a full reset.
Using Age-Based Sleep Needs Without Stress
Many parents type “how much sleep do babies need by age?” into a search bar after a few rough nights and hope for a magic fix. Age-based charts help as a compass, not as a strict rulebook.
A helpful way to use them is in three steps. First, find your baby’s age band and note the total daily hours. Second, see how close your current day looks to that band over a week, not just one day. Third, nudge one change at a time, such as earlier bedtime, slightly longer wake window, or a calmer wind-down before nap.
If sleep feels far off from the ranges and your baby seems tired or wired most of the time, a visit with your child’s doctor can bring tailored advice. Medical issues such as reflux, breathing problems, or allergies sometimes show up first as sleep trouble, and a doctor can sort out when extra checks make sense.
When Baby Sleep Charts Do Not Match Your Child
Some children sit near the low end or high end of the sleep range for their age yet still grow well and stay alert during the day. In those cases, the chart might say one thing while your child’s behavior says another. As long as your baby eats well, gains weight as expected, meets milestones, and seems settled when awake, small differences from the chart are usually fine.
Other times, life conditions shape sleep more than age. Families who share care among relatives, work night shifts, or live with noisy housing may see split nights or shorter naps. In those settings, leaning on routines, light cues, and calm pre-sleep habits can still protect a good share of the sleep your baby needs at each age.
When you feel unsure, bring sleep logs to your pediatric visit. A simple record of naps, bedtime, night wakings, and wake time over a week or two gives a clear picture and helps your baby’s doctor suggest changes that suit your child, not just the typical chart.
