But it's also the age when many families hit the so-called **"8-month regression"**: a patch of rougher nights that is actually the combination of two big milestones — the **peak of separation anxiety** and a **motor explosion** (crawling, pulling to stand). This guide covers how much an 8-month-old usually sleeps, how naps and wake windows look, a flexible schedule, what's behind this phase, and what to do when your baby stands up in the crib and can't lie back down. ## How much an 8-month-old sleeps In total, an 8-month-old sleeps about **12 to 15 hours a day**, counting night and naps, with the average around **14 hours**. Most of it happens **at night**, in a long stretch, and daytime sleep is down, in most cases, to **two naps**. As always, it's a wide range of normal: the best sign that things are fine isn't hitting a number, but a baby who eats well, gains weight, and is active and curious when awake. (For the full picture across ages, see the [how much sleep by age table](/en/blog/how-long-should-baby-sleep-by-age/).) ## Wake windows at 8 months The **[wake window](/en/blog/wake-windows-by-age/)** — how long your baby can comfortably stay awake between sleeps — is usually **2h45 to 3h45** at 8 months. On **2 naps**, windows are closer to **3 to 3.5 hours**, and the **last window of the day** (before night sleep) is the longest. Going much beyond that tends to leave the baby **overtired** — more wound up and harder to settle. At this stage, it's easy to mistake separation-anxiety bedtime protest for "not being tired": watch the **sleepy cues** (yawning, rubbing eyes, losing interest, getting fussier) instead of just timing. ## Naps at 8 months At 8 months, most babies are **settled on 2 naps a day** — one in the morning and one in the early afternoon, about **1 to 1.5 hours each**. Some are still wrapping up the 3-to-2 nap transition, and that's normal. The next big change — the move to **1 nap** — usually comes much later, between **12 and 18 months**. So at 8 months it's not the time to drop naps: protecting both helps hold the nights together, especially during the rougher sleep patch. ## A flexible one-day schedule There's no fixed schedule at 8 months. This example uses **2 naps and windows of ~3 to 3h45**. Use it as an elastic reference, not a rule: | Time (example) | What happens | |---|---| | 7:00 | Wakes and feeds | | 8:00 | Breakfast (solids) | | 10:00–11:15 | 1st nap | | 11:30 | Milk, awake time | | 12:30 | Lunch (solids) | | 14:15–15:30 | 2nd nap | | 15:45 | Milk, awake time | | 17:00 | Dinner (solids) | | 18:45 | Milk, calm routine | | 19:15–19:45 (varies) | Start of night sleep | | Overnight | 0–1 waking | Notice: **solids** now fill three meals and keep **taking up more space** across the first year — but **milk (breast or formula) is still the base of nutrition** at this stage. Let the shift happen at your baby's pace, without forcing it. ## Sleep at night At 8 months, many babies do a **long night stretch**, and several spend most of the night without asking to feed. Even so, **0 to 1 waking stays within normal** — the frequency varies a lot, and breastfed babies tend to feed more often. It's not the time to cut night feeds on your own. At this age, what **disrupts** nights often isn't hunger — it's usually the developmental phase (below), a tooth coming in, or a mistimed window leaving the baby overtired. Still, a growth spurt or variable solids intake can bring real hunger back, and new foods sometimes cause gas or constipation that disrupt sleep — worth considering before ruling out. ## The "8-month regression": separation + motor leaps Between **8 and 10 months**, a rougher sleep patch is common — more wakings, nap resistance, trouble falling asleep. Despite the nickname, **it's not really a regression**: it's two milestones happening at once: - **The peak of separation anxiety.** Object permanence has matured, and your baby now feels your absence keenly — including at bedtime. What helps: a predictable routine, short and calm goodbyes, and peekaboo during the day (which teaches that you always come back). - **A motor explosion.** Crawling, pulling to stand, and cruising along furniture are achievements your baby wants to **practice all the time** — including waking at night to train standing in the crib. What helps you get through it is **staying consistent** (a light routine, wake windows, safe sleep) rather than inventing new habits you don't want to keep. And, as always: if the worsening comes with fever, inconsolable crying, or signs of pain, think of a physical cause and see your pediatrician. ## When they stand up in the crib and can't lie down A classic at 8 months: the baby **stands up in the crib** — sometimes at night — and cries because they can't yet **get back down**. It's frustrating but temporary — it usually resolves in one to two weeks in most cases, though every baby has their own timing. What works: during the day, **practice the sit-down and lie-down movement from standing** with them, turning it into a game, so the skill becomes automatic. At night, when they stand up, **lay them down calmly, without turning it into a game or giving much attention**, and leave; if they stand again, repeat calmly and patiently. ## Safe sleep at 8 months At 8 months your baby sits, crawls, and starts to stand — and the crib needs to keep up. > Keep the **crib mattress at its lowest level** (essential now that your baby stands, so they can't fall out) and the crib **free of pillows, cushions, bumpers, and loose blankets** — including large toys that could serve as a "step." Your baby can sleep in whatever position they choose and, if they roll on their own during sleep, **you don't need to turn them back** — but you keep **placing them on their back to sleep**. To keep them warm, use a **sleep sack** instead of a blanket. Room-sharing (not bed-sharing) with parents is recommended for **at least the first 6 months**. ## What helps sleep at 8 months - **Keep a light, predictable routine** before sleep (bath, milk, low light, a song), in the same order — predictability soothes separation anxiety - **Protect the 2 naps and the wake windows**, so your baby doesn't reach night overtired - **Give plenty of awake motor practice** during the day (free floor time to crawl, practice sitting and lying down), so your baby "spends" the urge to train outside the crib - **Put your baby down drowsy but still awake** when you can — it helps them resettle on their own at wakings (which have several causes, not just one) On **sleep training**: from 4–6 months some more structured methods can be considered, and the decision is the family's — worth discussing with your pediatrician. None of it is mandatory. ## When to talk to your pediatrician Sleep at 8 months still varies, but it's worth talking to your pediatrician if: - Your baby is **very sleepy**, hard to wake, or **isn't gaining weight** as expected - Your baby **snores loudly**, pauses in breathing, or seems to work hard to breathe while asleep - The sleep trouble comes with **extreme irritability**, fever or other signs something's wrong - Your baby **doesn't sit without support, doesn't make sounds/babble**, or doesn't interact as expected (worth checking development) - You're **exhausted to the point of not coping** — asking for help is also caring for your baby ## What to expect next Eight months packs a lot in at once — 2 firm naps, separation at its peak, and the body learning to move. If sleep is rough right now, that's probably why, and it passes. In the coming months your baby gains balance, separation eases, and nights tend to firm up again. The trick stays the same as in the [7-month guide](/en/blog/baby-sleep-7-months/): go at your baby's pace, with wake windows, a light routine, safe sleep and patience. ## FAQ ### How much does an 8-month-old sleep per day? Usually about 12 to 15 hours a day counting night and naps, with the average around 14 hours. Most of it now happens at night, in a long stretch, and daytime sleep is down to 2 naps for most babies. If your baby is active, eating well and gaining weight, things are probably fine. ### How many naps does an 8-month-old take? Most are settled on 2 naps a day (morning and early afternoon), about 1 to 1.5 hours each. Some babies are still finishing the 3-to-2 nap transition, and that's fine. The move to 1 nap usually comes much later, between 12 and 18 months. ### What is the '8-month sleep regression'? It's a rougher sleep patch that tends to show up between 8 and 10 months, but it's not really a regression: it's the combination of two developmental milestones — the peak of separation anxiety and big motor leaps (crawling, pulling to stand). The baby wakes more, resists naps and wants to 'practice' the new skills, even at night. It's temporary and passes with consistency. ### My baby stands up in the crib and cries without knowing how to lie down. What do I do? It's very common at 8 months. During the day, teach and practice the sit-down/lie-down movement from standing, so they gain independence. At night, lay them down calmly and without turning it into a game; if they stand up again, repeat calmly. It usually resolves in one to two weeks, but it varies from baby to baby. ### What's the wake window (awake time) at 8 months? Around 2h45 to 3h45 awake between sleeps, with the last window of the day (before bed) being the longest. On 2 naps, windows are closer to 3 to 3.5 hours. Watching sleepy cues still beats watching the clock.
