Baby Sleep Schedule by Age: From Newborn to 12 Months

Sleep is one of the most magical — and challenging — parts of your baby’s first year. Every mother quickly learns that baby sleep is not just about hours, but about rhythm, growth, and connection.

Understanding your baby’s sleep schedule by age helps you build comforting routines and create the right balance between naps, feedings, and awake time.

Baby Sleep Patterns by Age

From the moment your baby is born, sleep happens in mysterious cycles. A newborn can sleep up to 16–18 hours a day, divided into short naps that follow no clear rhythm. But as weeks pass, sleep starts taking shape — little by little.

Newborn Sleep Patterns by Week

During the first four weeks, babies sleep most of the time, waking only for feeding and diaper changes. Their sleep cycles are short — about 40 to 50 minutes — meaning they move from deep sleep to light sleep quickly.

• Week 1–2: 16–18 hours total, with frequent waking for feeding.
• Week 3–4: Slightly longer awake windows (45–60 minutes).
• Tip: Focus on creating a calm bedtime environment with soft lights and gentle white noise.

Sleep Cycle Length by Age

As babies grow, their sleep cycles lengthen and become more predictable. At 3 months, a baby’s sleep cycle is about 50–60 minutes, and by 6 months, it extends to around 70 minutes. Each cycle includes both deep (quiet) sleep and active (REM) sleep, just like adults, but in shorter spans.

Baby Sleep Cycle Length (Month-by-Month Overview)

• 0–3 months: 40–50 minutes per sleep cycle.
• 4–6 months: 60–70 minutes per cycle.
• 7–9 months: 70–80 minutes per cycle.
• 10–12 months: 90 minutes per cycle (similar to adults).

By understanding these sleep cycles, parents can time naps and bedtime transitions more smoothly. If you’ve ever wondered, “Why does my baby wake up after exactly 45 minutes?”, now you know — it’s simply the end of a sleep cycle!

Baby Sleep Patterns by Month

Every baby is unique, but most follow a general pattern of sleep development over the first year:

• Month 1–2: Frequent naps day and night, totaling up to 16 hours of sleep.
• Month 3–4: Longer nighttime stretches (4–6 hours) begin to appear.
• Month 5–6: Baby may start sleeping 6–8 hours at night with 3–4 daytime naps.
• Month 7–9: Total sleep around 14–15 hours; naps reduce to 2–3.
• Month 10–12: Baby can sleep through most of the night, with two regular naps.

Don’t worry if your baby’s sleep doesn’t match this exactly — these are averages, not rules. What matters most is creating a soothing bedtime ritual that feels natural for your family.

Baby Sleep Cycle: When to Put Down

Knowing when to lay your baby down can make all the difference. The sweet spot is when your baby is drowsy but not yet asleep — usually 10–15 minutes after showing early sleep cues (yawning, rubbing eyes, or fussing softly).

🍼 Baby Sleep Schedule by Age (0–12 Months)

Every month of your baby’s first year brings new sleep changes. Understanding these natural shifts helps parents adapt gently — instead of fighting sleepless nights with frustration. Below is a simple month-by-month sleep guide you can follow at home.

Age	Total Sleep (24h)	Night Sleep	Naps (Daytime)
0–1 month	16–18 hours	8–9 hours	6–7 short naps
2–3 months	15–17 hours	8–10 hours (broken)	4–5 naps
4–5 months	14–16 hours	9–10 hours	3–4 naps
6–7 months	14–15 hours	10–11 hours	3 naps
8–9 months	13–15 hours	10–11 hours	2–3 naps
10–12 months	12–14 hours	10–12 hours (mostly uninterrupted)	2 naps

🌙 Sleep Tips by Age

Newborn (0–2 months)

Newborns need to feel safe and snug. Keep the room dim, swaddle gently, and follow baby’s natural rhythm rather than enforcing a strict bedtime. Avoid loud noises and overstimulation.

3–4 months

Your baby begins to recognize day and night. Introduce a bedtime routine: bath, gentle massage, lullaby, feed, and sleep. Avoid screens and bright lights an hour before bed.

5–6 months

This is when many babies start sleeping longer stretches at night. A consistent nap schedule helps. Day naps should be in bright, airy spaces, while night sleep should be in calm darkness.

7–9 months

Babies may face “sleep regressions” — sudden waking during the night. Don’t worry; it’s part of cognitive growth. Offer reassurance and comfort without rushing to feed each time.

10–12 months

By the first birthday, your baby’s sleep rhythm is well-established. Two naps (morning and afternoon) are enough. Focus on consistency — same bedtime, same song, same hugs.

🧸 Recommended Sleep Hours by Age

• Newborn (0–2 months): 16–18 hours daily.
• 3–5 months: 14–16 hours daily.
• 6–9 months: 13–15 hours daily.
• 10–12 months: 12–14 hours daily.

Remember: some babies sleep more, others less. It’s not a contest — it’s about what makes your little one calm and rested. Follow your baby’s cues rather than comparing with charts.

💤 Average Sleep Duration by Age

Most babies sleep in cycles of 45–90 minutes, and it’s natural for them to wake briefly between cycles. The key is helping your baby learn to self-soothe — not forcing continuous sleep.

💡 Practical Tips for a Peaceful Baby Sleep Routine

• Establish a bedtime routine: Babies thrive on predictability. Try a warm bath, soft music, and a dim room each night.
• Keep nap times consistent: A regular daytime sleep pattern improves nighttime sleep quality.
• Watch for sleepy cues: Yawning, rubbing eyes, or fussiness mean your baby needs rest — don’t wait too long.
• Create a calm environment: Use white noise or a gentle lullaby to soothe your baby into slumber.
• Encourage self-soothing: Place your baby down drowsy but awake, allowing them to learn how to fall asleep independently.

🍼 Common Sleep Challenges and Gentle Solutions

Every baby is unique, and sleep struggles are part of the journey. Here’s how to handle a few common ones:

• Frequent night waking: Ensure your baby isn’t too cold, too warm, or overstimulated. Avoid bright lights during nighttime feeds.
• Short naps: Try a darker room and calming pre-nap routine to extend nap length.
• Sleep regression (especially around 4 months): Stick to your routine, offer comfort, and know that it’s temporary.
• Baby fighting sleep: Overstimulation before bedtime is often the cause — keep evenings quiet and cozy.
