Eight months brings a well-established 2-nap routine — but it's also prime time for the 8-month sleep regression (sometimes called the 8-10 month regression). This developmental leap, tied to major cognitive and motor milestones like crawling, pulling to stand, and object permanence, can disrupt sleep even for babies who have been sleeping well.
💡 8 Months Sleep at a Glance
Total sleep: 11–14 hours per day
Naps: 2 naps
Wake windows: 2.5–3.5 hours between sleeps
Nighttime: 10–12 hours
An 8-month-old needs 11–14 hours of total sleep per day on a 2-nap schedule. Wake windows are 2.5–3.5 hours. The 8-month regression — linked to developmental leaps in motor skills, language, and object permanence — can cause increased night waking and nap disruption for 2–6 weeks.
⚠️ 8-Month Sleep Regression
The 8-month sleep regression (sometimes spanning 8–10 months) is driven by major developmental leaps: crawling, pulling to stand, object permanence, and separation anxiety. It's temporary — most families see improvement within 2–4 weeks with a consistent routine.
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.
| Time | Activity | Notes |
|---|---|---|
| 6:30 AM | Wake & Feed | Morning wake |
| 9:00 AM | Nap 1 | After 2.5h |
| 10:30 AM | Wake | Nap ~1.5h |
| 2:00 PM | Nap 2 | After 3.5h |
| 3:30 PM | Wake | Nap ~1.5h |
| 5:00 PM | Dinner (solids) | 3 meals/day by 8m |
| 7:00 PM | Bedtime Routine | After 3.5h from last nap |
| 7:30 PM | Down for night | 10–12h if no regression |
| Time | Activity | Notes |
|---|---|---|
| 7:00 AM | Wake & Feed | Start of day |
| 9:30 AM | Nap 1 | After 2.5h |
| 11:00 AM | Wake | Nap ~1.5h |
| 2:30 PM | Nap 2 | After 3.5h |
| 4:00 PM | Wake | Nap ~1.5h |
| 6:00 PM | Dinner | Solids + nursing/bottle |
| 7:30 PM | Bedtime | After ~3.5h from last nap |
A wake window is the period of time a baby can comfortably stay awake between sleeps. At 8 months, the ideal window is 2.5–3.5 hours. Keeping wake windows consistent is one of the most effective tools for improving nap quality and nighttime sleep.
✓ 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.
Increased night waking, early morning rising, and nap refusal are all signs. This regression is driven by developmental leaps — crawling, pulling to stand, separation anxiety, and emerging object permanence. It's temporary (usually 2–4 weeks) but can be intense.
Object permanence is developing, meaning baby now knows you exist even when you leave the room — and may protest loudly. A consistent routine and brief, calm goodbyes help.
Some 8-month-olds start pushing back on nap 2. Try lengthening the wake window slightly before nap 2. If resistance is severe, don't jump to 1 nap — most babies aren't ready until 14–18 months.
Babies learning to crawl or pull to stand often practice in their crib at night. Ensure they can get into the position independently (e.g., from sitting back to lying) to avoid getting stuck.
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.
No schedule is permanent — as your baby grows, wake windows lengthen and nap count decreases. Signs it may be time to adjust:
When adjusting, change one thing at a time and give 5–7 days for your baby to adapt before making further changes.
How many naps does an 8-month-old need?
An 8-month-old takes 2 naps per day, each 1–2 hours long. Total sleep is 11–14 hours. During the 8-month regression, naps may temporarily shorten.
What are wake windows for an 8-month-old?
Wake windows at 8 months are 2.5–3.5 hours. The first wake window is often 2.5h and the last one before bed extends to 3–3.5h.
What time should an 8-month-old nap?
With a 7 AM wake time: Nap 1 around 9:30 AM, Nap 2 around 2:30 PM, bedtime around 7:30 PM. Nap 2 should end by 4:00–4:30 PM to protect nighttime sleep.
