Baby sleep needs range by age—newborns average 14–17 hours, while 4–12-month infants need 12–16 hours in 24 hours, including naps.
New parents ask one question over and over: how much sleep should my baby get? The honest answer is “by age and by rhythm.” Newborns rack up long totals in short bursts. By four months, nights start to lengthen and naps start to organize. The ranges below come from medical groups that study kids’ sleep and health. You’ll also find realistic nap patterns, sample schedules, and safety rules that keep nights calm.
How Much Sleep Should My Baby Get? By Age And Stage
The chart below pulls together widely cited ranges for total sleep in a 24-hour day and shows a typical split between night sleep and naps. Every baby lands a little differently, but this gives you a solid target to work from.
| Age | Total Sleep (24h) | Typical Night & Nap Split |
|---|---|---|
| 0–3 Months (Newborn) | 14–17 hours | Nights 8–9h in chunks; 4–6 naps totaling 6–8h |
| 4–6 Months | 12–16 hours | Nights 9–11h; 3–4 naps totaling 3–5h |
| 7–9 Months | 12–16 hours | Nights 10–11h; 2–3 naps totaling 3–4h |
| 10–12 Months | 12–16 hours | Nights 10–12h; 2 naps totaling 2–4h |
| 13–18 Months | 11–14 hours | Nights 10–12h; 1–2 naps totaling 1–3h |
| 19–24 Months | 11–14 hours | Nights 10–12h; 1 nap ~1–3h |
| 2–3 Years | 10–13 hours | Nights 10–11h; 0–1 nap ~1–2h |
How Much Sleep Your Baby Should Get By Age (Quick Chart)
For medical context behind those ranges, pediatric sleep experts recommend 12–16 total hours per day for infants 4–12 months, 11–14 hours for toddlers 1–2 years, and 10–13 hours for ages 3–5. Those totals include naps. That guidance is based on outcomes like growth, learning, and behavior.
What Shapes Baby Sleep In The First Year
Newborn Rhythm (0–3 Months)
Newborns don’t show steady day-night cycles yet. Feeding drives the day, and sleep comes in short stretches. Long totals are normal; long stretches at night are not expected. If you’re asking “how much sleep should my baby get?” at this stage, aim for the range and protect naps rather than chasing strict clocks.
Building A 24-Hour Pattern (4–6 Months)
By four months, many babies start linking sleep cycles. Nights lengthen, and naps consolidate from many short catnaps to three or four regular naps. Calmer bedtime routines begin to pay off now.
From Three Naps To Two (6–9 Months)
Two daytime naps often land late morning and mid-afternoon. Early evening “catnaps” fade. Teething and new skills can shake things up. Hold the routine steady and let the range guide you.
Toward A One-Nap Day (10–14 Months)
Most babies keep two naps through the first birthday, then slide to one long lunch-time nap somewhere between 13 and 18 months. When bedtime drifts late or your baby parties at 4 a.m., it might be time to trim nap length or move to one nap.
Safe Sleep Rules You Should Always Follow
Hours matter, but safety matters more. Place your baby on the back for every sleep, use a firm, flat surface (crib, bassinet, or play yard), and keep the sleep space clear of pillows, bumpers, and loose blankets. Room-share without bed-sharing for the first months. Pacifiers at sleep times can help reduce risk once breastfeeding is settled. You can read the current pediatric guidance here: AAP safe sleep recommendations and the CDC page on safe sleep.
Wake Windows And Cues (Use Both)
Wake windows help you time naps. Cues help you adjust them. Use these as soft guides and watch your baby’s signals.
Typical Wake Windows
- 0–8 weeks: 45–60 minutes
- 2–3 months: 60–90 minutes
- 4–5 months: 90–120 minutes
- 6–7 months: 2–3 hours
- 8–10 months: 2.5–3.5 hours
- 11–14 months: 3–4.5 hours
Sleepy Cues To Watch
Red brows, zoning out, slower movements, and a quiet stare show up early. Big yawns and eye rubbing show up late. If you miss the window, overtired energy can kick in and make settling tough.
Night Feeds And Stretch Lengths
Feeding and sleep change together. In the early months, babies wake often to eat. As feeds spread out and weight gain is steady, night stretches usually lengthen. Some babies sleep 6–8 hours by six months; many still need a feeding or two. Your pediatrician’s guidance on growth and feeding should set the pace.
When Totals Fall Short (Or Run Long)
Common Signs Your Baby Needs More Sleep
- Short catnaps all day and short night stretches
- Frequent early-morning wake-ups
- Crankiness in late afternoon even with naps
- Hard time settling, then short naps
Try an earlier bedtime, slightly shorter wake windows, and a darker room for naps. Protect one longer nap to anchor the day.
When Sleep Totals Seem Too High
Illness, growth spurts, or a busy day can add hours. If long sleep comes with low energy, poor feeding, or other symptoms, call your pediatrician.
Build A Routine That Sticks
Evenings
Pick a steady bedtime window and run the same short sequence every night: bath, feed, story, crib. Keep lights low and voices calm. A simple routine is the best cue your baby can get.
Days
Step outside for daylight in the morning. Keep naps in a dark, quiet space. Try to start naps at roughly the same times, but use cues when your baby needs earlier or later starts.
Age-By-Age Nap Patterns
Use these ranges as a planning tool, not a test. If your baby lands a little off the template yet wakes happy and feeds well, you’re doing fine.
| Age | Daytime Nap Pattern | Sample Bedtime & Night |
|---|---|---|
| 0–8 Weeks | 4–6 naps; lengths vary from 20–120 min | Bedtime floats; nights in 2–4h chunks |
| 3–4 Months | 3–4 naps; aim for first nap ~1.5h after wake | Bedtime 7–9 p.m.; 1–3 night feeds common |
| 5–6 Months | 3 naps; last nap is a short bridge | Bedtime 7–8 p.m.; longer first stretch |
| 7–9 Months | 2–3 naps; many shift to 2 stable naps | Bedtime 7–8 p.m.; 0–2 night feeds |
| 10–12 Months | 2 naps ~60–90 min each | Bedtime 7–8 p.m.; early waking if naps run late |
| 13–18 Months | Transition to 1 midday nap ~90–120 min | Bedtime ~7 p.m.; protect the single nap |
| 19–36 Months | 1 nap 60–120 min (drops by preschool) | Bedtime 7–8 p.m.; quiet time if nap is gone |
Sample 24-Hour Days
6 Months (Two Or Three Naps)
7:00 a.m. wake → 9:00–10:00 a.m. nap → 12:30–1:30 p.m. nap → 4:00–4:30 p.m. catnap if needed → 7:30 p.m. bedtime. Night feed as advised by your pediatrician.
9 Months (Two Naps)
7:00 a.m. wake → 9:30–10:30 a.m. nap → 2:00–3:00 p.m. nap → 7:30 p.m. bedtime. If mornings start early, bring the first nap earlier and keep bedtime steady.
14 Months (One Nap)
7:00 a.m. wake → 12:30–2:00 p.m. nap → 7:00 p.m. bedtime. On rough days, cap the nap and pull bedtime earlier.
When To Call Your Pediatrician
- Snoring, gasping, or long, repeated pauses in breathing during sleep
- Persistent total sleep well below the age range with daytime meltdown cycles
- Sleep that only happens upright in a seat or on someone’s chest
- Feeding or growth concerns linked with night wake-ups
Your doctor can screen for reflux, allergies, breathing issues, or iron deficiency and can tailor a plan that fits your baby.
Frequently Missed Basics That Make A Big Difference
Light And Timing
Bright mornings anchor the body clock. Dim evenings cue melatonin. Move bright toys out of the crib and keep the room dark for sleep.
Temperature And Clothing
Keep the room comfortable and avoid overheating. Dress your baby in one more layer than you wear, then add or remove a layer if hands and chest feel too cool or warm.
Independent Starts
Lay your baby down drowsy but awake when you can. Even one start per day in the crib helps them link cycles later at night.
What The Research Says About Sleep Ranges
Large expert groups have reviewed hundreds of studies to set age-based ranges that support healthy growth, behavior, and learning. For infants 4–12 months, totals of 12–16 hours per 24 hours are linked with better outcomes. For toddlers 1–2 years, 11–14 hours line up with sharper daytime mood and learning. You can read an overview of those ranges on the AAP’s HealthyChildren hours page.
Putting It All Together
Pick the right range for your baby’s age. Shape your day around two or three steady nap anchors. Keep the bedtime window steady. Protect safe sleep rules every time. If totals drift, adjust wake windows and bring bedtime earlier for a week. That steady approach answers the real-world version of “how much sleep should my baby get?” and keeps your days smoother.
