4-Month-Old Nap Schedule: Sample Schedule, Wake Windows & Tips
On this page
Four months is one of the most significant sleep milestones of the first year — and often the most challenging. The 4-month sleep regression hits right around now as your baby's sleep architecture permanently matures into adult-like cycles. Naps may shorten, nighttime waking may increase, and your previously "good sleeper" may suddenly seem unable to settle. This is developmental, not a problem to fix. For a complete overview of how this fits into the first year, see our complete baby sleep schedule by age.
How Much Sleep Does a 4 Months Need?
4 Months Sleep at a Glance
Total sleep: 12–16 hours per day
Naps: 3–4 naps
Wake windows: 90–120 min between sleeps
Nighttime: May fragment due to regression
A 4-month-old needs 12–16 hours of total sleep per day across 3–4 naps. Wake windows are stretching to 90–120 minutes. However, the 4-month sleep regression often disrupts what was working — naps may cap at 30–45 minutes and nighttime waking may increase significantly. This is a neurological milestone, not regression from prior good habits.
4-Month Sleep Regression
The 4-month sleep regression hits right around now. It's a permanent and healthy change in your baby's sleep architecture — not something you did wrong. Most families see improvement within 2–6 weeks. Learn more about the 4-month regression →
Sample 4 Months Nap Schedule
The following sample schedules are starting points — adjust based on your baby's natural wake time and how long each nap runs. Watch cues, not just the clock.
Early Riser (6:30 AM start)
| Time | Activity | Notes |
|---|---|---|
| 6:30 AM | Wake & Feed | Morning wake |
| 8:00 AM | Nap 1 | After 90 min |
| 9:30 AM | Wake & Feed | Nap may be short — 30–45 min |
| 11:15 AM | Nap 2 | After ~105 min |
| 12:45 PM | Wake & Feed | Midday |
| 2:30 PM | Nap 3 | After ~105 min |
| 4:00 PM | Wake | Afternoon wake |
| 5:30 PM | Nap 4 (catnap, if needed) | 30 min only |
| 6:00 PM | Wake | Brief before bedtime |
| 7:00 PM | Bedtime Routine | Bath, feed, dark room, white noise |
| 7:30 PM | Down for night | Regression: may wake multiple times |
| 11:00 PM | Night wake (regression) | Offer comfort/feed if needed |
| 2:00 AM | Night wake (regression) | Normal during regression |
| 4:30 AM | Night wake / early feed | Normal during regression |
Average (7:00 AM start)
| Time | Activity | Notes |
|---|---|---|
| 7:00 AM | Wake & Feed | Start of day |
| 8:30 AM | Nap 1 | After 90 min |
| 10:00 AM | Wake & Feed | Often a short 30 min nap |
| 11:45 AM | Nap 2 | After ~105 min |
| 1:15 PM | Wake & Feed | Midday |
| 3:00 PM | Nap 3 | After ~105 min |
| 4:30 PM | Wake | Afternoon |
| 5:45 PM | Catnap (optional) | If gap to bedtime is too long |
| 7:30 PM | Bedtime | Feed, drowsy-but-awake |
| 11:30 PM | Night wake | Regression wake |
| 3:00 AM | Night wake | Regression wake |
Wake Windows Explained
A wake window is the period of time a baby can comfortably stay awake between sleeps. At 4 months, the ideal window is 90–120 min. Keeping wake windows consistent is one of the most effective tools for improving nap quality and nighttime sleep.
Tired Cues to Watch For
- Yawning — usually the earliest cue; don't ignore it
- Eye rubbing — a reliable mid-stage cue
- Fussiness and irritability — late cue; act quickly when you see this
- Losing interest in toys — staring blankly or disengaging from play
- Pulling at ears — self-soothing behavior in some babies
- Red eyebrows or eyelids — skin flushing from tiredness
The Goal: Drowsy But Awake
Aim to put baby down when they are drowsy but still awake. This gives them the opportunity to practice the last step of falling asleep independently — the same skill they'll need when they rouse between sleep cycles at night.
Common Nap Problems at 4 Months (Regression)
The 4-month sleep regression
This is the #1 issue at 4 months. Caused by permanent maturation of sleep architecture, it means your baby now cycles through light sleep and wakes fully between cycles. This is normal and temporary — most families see improvement in 2–6 weeks.
Naps capping at 30–45 min
Short naps are the hallmark of the 4-month regression. Your baby is waking at the end of one sleep cycle. Try re-settling with a hand on chest or gentle shush — some babies can be guided back into a second cycle.
Increased nighttime waking
Multiple night wakings during the regression are typical. Maintain consistency in how you respond, and try to put baby down drowsy-but-awake to encourage self-settling.
Shorter wake windows needed
Some babies actually need slightly shorter wake windows during the regression — watch cues closely and don't push past 90–100 min if baby seems tired earlier.
Sleep Environment Tips
A consistent sleep environment is one of the most powerful tools for improving nap length and quality. Even if you can't control timing perfectly, you can always control the sleep space.
- Dark room: Use blackout curtains. Even small amounts of light can inhibit melatonin production and shorten naps.
- White noise (optional): White noise is optional. Use low volume, a distant position and limited exposure. See AAP noise guidance.
- Temperature: Aim for 68–72°F (20–22°C). Overheating is both a safety concern and a sleep disruptor.
- Consistent location: Napping in the same place whenever possible helps baby learn that this space means sleep.
- Safe sleep: Always follow AAP safe sleep guidelines — firm, flat surface; no loose bedding, bumpers, or positioners.
When to Adjust the Schedule
No schedule is permanent — as your baby grows, wake windows lengthen and nap count decreases. Signs it may be time to adjust:
- Baby is consistently taking a long time (30+ minutes) to fall asleep for naps
- Baby wakes from naps seemingly well-rested after only 30–45 minutes
- Baby is waking earlier than 6 AM consistently
- Nap timing is significantly disrupting bedtime
- Baby seems overtired at bedtime despite following the schedule
When adjusting, change one thing at a time and give 5–7 days for your baby to adapt before making further changes.
Frequently Asked Questions
How many naps does a 4-month-old need?
A 4-month-old typically needs 3–4 naps per day. During the 4-month sleep regression, naps may shorten to 30–45 minutes each. Total sleep is 12–16 hours in 24 hours.
What are wake windows for a 4-month-old?
Wake windows at 4 months are 90–120 minutes. During the regression, some babies do better with slightly shorter windows (80–90 min). Watch for tired cues rather than rigidly following the clock.
What time should a 4-month-old nap?
A typical 4-month nap schedule with a 7 AM wake time: Nap 1 around 8:30 AM, Nap 2 around 11:30 AM, Nap 3 around 2:30 PM, and bedtime around 7:00–7:30 PM.
