The 8-Month Sleep Regression is a normal developmental storm: a baby who slept well suddenly starts waking multiple times at night, fighting naps, and struggling at bedtime. This temporary “storm” typically hits between 7 and 9 months, driven primarily by strong separation anxiety and major developmental milestones like crawling and standing. If you have previously navigated the 4-Month Sleep Regression or the 6-Month Sleep Regression, you know consistency is key.
This post will give you a complete, streamlined plan on How to survive 8 month sleep regression and teaches you How to get 8 month old to sleep through the night using simple, gentle methods to fix night wakings, improve naps, and ease separation anxiety starting tonight.
📖 Executive Summary: 8-Month Sleep Regression (What Works)
The 8-Month Sleep Regression is a temporary phase, usually lasting 2–6 weeks. It is caused by rapid brain development and new skills, primarily separation anxiety, crawling, and standing. Remember, it’s a sign of progress, not failure.
The Most Effective Fix: Consistently teach your baby independent sleep (self-soothing).
- Daytime Focus: Optimize wake windows (2–3 hours) and provide ample time for practicing new motor skills. (Why it works: Prevents overtiredness, the number one cause of night wakings.)
Nighttime Focus: Use the Sleepy-But-Awake Rule consistently and apply the Pause Rule (wait 1–5 minutes before intervening) to encourage self-soothing. (Why it works: Babies gradually learn that the crib is a safe place to fall asleep on their own.)
Understanding the 8-Month Sleep Regression & Progression
Although it’s called a “regression,” it’s actually a sign of healthy development [1]. Your baby’s sleep is disrupted because their brain is growing rapidly and practicing new skills. This phase is better understood as a sleep progression.
👉 Note: After the 8-month sleep regression, you may also encounter the 12-month sleep regression (due to walking and a shift to a single nap).
8-Month Sleep Regression Signs
- Frequent night wakings after previously long stretches
- Shortened or skipped naps
- Bedtime battles or trouble settling
- Increased clinginess and separation anxiety
- Practicing new skills (crawling, pulling up) in the crib
- Restlessness despite being tired
Causes of 8-Month Sleep Regression: Why is my 8 month old waking multiple times at night?
The 8-month sleep regression is usually triggered by a mix of developmental growth and emotional changes. Common causes include:
- Separation Anxiety: At this age babies realize parents can leave—this awareness can trigger waking and crying when they find themselves alone at night.
- Developmental Milestones: Active learning like crawling, standing or babbling can make it harder to settle at bedtime.
- Overtiredness or overstimulation: Too much activity or delayed naps can make it harder for your baby to fall and stay asleep.
- Teething: Gum discomfort can worsen sleep. Teething often overlaps with this regression.
- Growth spurts: Extra hunger or increased feeding at night can disturb normal sleep patterns [2].
How Long Does 8-Month Sleep Regression Last?
Sleep disruptions at this age generally last 2 to 6 weeks [1]. The exact length depends on how quickly your baby masters their new skills and how consistently you address the underlying causes (especially separation anxiety and independent sleep).

⭐ Quick Overview ⭐
The 8-Month Sleep Solution
8 Focused Steps for a smoother night’s sleep. 🚀
Step 1
Fix Nap Timing ⏰
Maintain the 2-nap structure. Ensure the last nap ends 3.5–4 hours before bedtime to build strong sleep pressure.
Step 2
Ease Separation Anxiety 💞
Offer extra cuddles and play peek-a-boo to fill their emotional tank and build trust.
Step 3
Manage New Skills 🤸♀️
Dedicate playtime to practicing crawling, standing, and cruising. Mastery during the day reduces nighttime “practice.”
Step 4
Drowsy, But Awake 🛌
Place your baby in the crib when they are drowsy but not fully asleep for naps and bedtime.
Step 5
Optimize the Sleep Environment 😴
Keep the room cool (20–22°C / 68–72°F), dark, and use soothing sound to mask outside noise.
Step 6
Stick to the Bedtime Routine 🧸
Follow the same calming sequence nightly (bath, lotion, feed, read) to cue sleep.
Step 7
Adjust Night Feeds 🍼
Boost calories in the day and gradually reduce night feeds to encourage consolidated sleep.
Step 8
Rule Out Discomfort/Pain 🌡️
Address teething or illness pain gently before bedtime.
✅ The Core Strategy: Consistency Meets Development
This plan addresses major developmental shifts and promotes self-soothing through consistent routines and a secure environment.
🚨 Key Takeaways
Timeline: Regressions are temporary—commit to the plan for 14 days consistently. Self-Care: Take care of yourself during this demanding phase.
Step 1: Reset the Nap Schedule
A restful night begins with well-planned daytime naps. Setting the right schedule prevents overtiredness, which is the number one cause of night wakings in the 8-Month Sleep Regression .
The Fix:
- Follow the 2-Nap Transition: At 8 months, most babies transitioning from three naps to two. If you try to keep that third nap, your baby may become overtired at bedtime and wake more often during the night.
- Set the Nighttime Buffer: End the last nap at least 3–4 hours before bedtime. Napping too close to the night makes it harder for your baby to build enough sleep pressure to fall and stay asleep.
Step 2: Navigate Separation Anxiety (Connection Strategy)
Around 8 months, babies often start experiencing separation anxiety. This happens because they now understand object permanence—they know you exist even when you are not in sight. When you leave the room, they realize you’re gone and may feel scared or upset, often leading to more frequent night wakings as they seek comfort and reassurance.
The Fix:
- Boost Daytime Connection: Spend extra one-on-one time during the day, focusing on cuddles and positive interaction. A baby with a full “connection cup” is less likely to panic when you leave at night.
- The Peek-a-Boo Principle: Before bedtime, play simple games like “peek-a-boo” where you leave and come back quickly. This teaches your baby that you always return and helps them sleep independently.
Step 3: Manage the New Skills with Daytime Practice
When babies learn to crawl or stand, they often do it in their sleep! They wake up, practice, and then cry because they can’t figure out how to get back down, This can cause repeated night wakings.
The Fix:
- Practice, Practice, Practice: Let your baby practice new skills like standing and crawling a lot during the day with your supervision. Daytime practice helps them learn safely, build confidence, and use up energy, so they’re less likely to wake at night to try new skills.
- Nighttime Rule: If they stand and cry at night, calmly put them back down without talking or cuddling, then immediately leave the room. This teaches them that nighttime is for sleeping, not for practicing.
Step 4: Reinforce Independent Sleep
The goal is to help your baby learn to fall asleep independently, without needing your physical presence, which can also reduce frequent night wakings [3, 4].
The Fix:
- Drowsy but Awake Rule: Put your baby in the crib when they are sleepy but still awake, both for naps and bedtime.
- Standing Rule: If your baby stands up and cries, do not rush in to lay them down immediately. Give them a few minutes to figure it out themselves. If needed, gently lay them down once and offer calm words of comfort while they remain in the crib.
Step 5: Optimize the Sleep-Friendly Room
A calm and comfortable sleep space helps your baby settle more easily, sleep longer, and wake less often during the night.
The Fix:
- Keep it dark: Use blackout curtains and dim lights 30–60 minutes before bedtime.
- Maintain a comfortable temperature: Keep the room around 20–22°C (68–72°F) and avoid heavy blankets or overheating.
- Reduce noise: Use white noise or close doors and windows to block household sounds.
Step 6: Stick to the Bedtime Routine
Consistency is your best friend right now. A simple, repeated routine helps your baby feel safe, reduces separation anxiety, and can lead to fewer night wakings.
The Fix:
- Follow the Sleep Script: Do the same bedtime routine every night—bath, story, quiet song, and a final cuddle. This tells your baby’s brain it’s time to sleep.
- The Travel Rule: Your routine is non-negotiable! Even on vacation or at Grandma’s house, mimic the steps as closely as possible to provide comforting familiarity during an unsettling time.
Step 7: Manage Night Feeding
A healthy 8-month-old typically does not need frequent nighttime feedings. If they wake up to eat, it’s usually more about habit or seeking comfort than an actual need. Always consult your pediatrician if you have concerns about your baby’s weight or feeding.
The Fix:
- Load the Calories: Give them plenty of food during the day. Make sure they eat well right before bed.
- The Gradual Reduction Strategy: If they wake up to eat, slowly give them less milk or feed them for a shorter time over several nights. This helps stop the habit of eating to fall asleep.
Step 8: Address Discomfort
Teething or minor illnesses can disturb your baby’s sleep, causing frequent wake-ups and frustration for both you and your little one.
The Fix:
- Pre-Bed Checkup: Before bedtime, check for any signs of teething or illness that might disturb sleep.
- Soothe Teething Pain: To ease teething discomfort, use cool teething toys or a safe pain reliever, but always use the one recommended by your pediatrician. Addressing pain before sleep gives your baby a better chance of staying asleep.
😴 Quick Fix Tips
- Keep your bedtime routine consistent.
- Avoid starting new sleep habits.
- Adjust wake windows carefully to prevent overtiredness.
- Let your baby practice new skills during the day.
- Offer full, calm feeds.
- Maintain a quiet and dark environment.
- Try an earlier bedtime.
- Stay patient — it’s temporary.
8-Month-Old Sleep Schedule (Two-Nap Focus)
Use this chart as a flexible guide, not a strict schedule. Follow your baby’s cues!
Time Range (Flexible) Activity Wake Window (Approx.) Nap Duration (Approx.) Notes 6:30 AM – 7:30 AM Wake Up & First Feed 2.5 hours — Longer wake window starts the day; expose baby to bright light. 9:00 AM – 10:00 AM Morning Nap 1 2.5–3 hours 1–1.5 hours This is the first of two critical naps; ensure a dark environment. 11:00 AM – 12:00 PM Feed & Play 3–3.5 hours — Use this window for solids, floor time, and active play. 1:30 PM – 2:30 PM Midday Nap 2 3–3.5 hours 1–1.5 hours The second and final nap. Focus on maximum sleep consolidation. 3:30 PM – 4:30 PM Feed & Play 3.5–4 hours — Last wake window is the longest, necessary for building night sleep pressure. 7:00 PM – 7:30 PM Bedtime Routine 20–30 mins — Start the routine 3.5-4 hours after Nap 2 ended (e.g., if Nap 2 ended at 3 PM, start routine at 6:30 PM). 7:30 PM – 8:30 PM Night Sleep Begins — 11–12 hours total Most 8-month-olds can sleep through the night with minimal or no feeds.
Remember:
- Total Sleep: 14–15 hours (11–12 night / 2.5–3.5 day).
- Wake Windows: Aim for 2.5 to 3.5 hours between sleep periods.
- Naps: Most babies are firmly on a 2-nap schedule. Dropping the third nap too early can cause regression.
- Bedtime: An earlier bedtime (7:00 PM – 8:00 PM) is crucial for preventing overtiredness.
When the Plan Is not Working: Gentle Sleep Training for the 8-Month Regression
If the above plan has not resolved the sleep regression after 2-3 weeks, you may need a gentle, consistent sleep training method to solidify independent sleep habits [3]

Parental Self-Care: You Matter Too
Sleep regressions can be stressful for everyone. You are not failing; you are navigating a temporary, normal developmental change. Taking care of yourself is just as important as helping your baby sleep.
Here are some practical ways to protect your rest and mental well-being:
- Nap when your baby naps – even short naps can make a big difference.
- Share night duties – alternate night waking responsibilities with your partner to avoid burnout.
- Practice quick relaxation techniques – deep breathing, stretching, or a 5-minute mindfulness break can reduce stress.
- Limit caffeine – it may help temporarily, but too much can interfere with your own sleep schedule.
- Accept help – let family or friends assist with chores, meals, or babysitting so you can rest.
Remember: your well-being directly supports your baby’s sleep. A calm, rested parent makes nighttime transitions easier.
What NOT to Do During Sleep Regression
- Frequent schedule changes: Constantly shifting bedtime or naps confuses your baby.
- Comforting every cry: Rocking or feeding every time stops them from learning to self-soothe.
- Overstimulation before bed: Too much play, bright lights, or screens makes it harder to wind down.
- Skipping naps: Missing daytime sleep can lead to overtiredness and more night waking.
- Forgetting it’s temporary: Sleep regression is normal and short-term—don’t stress or change routines unnecessarily.
- Ignoring the environment: Noisy, bright, or warm rooms can disrupt sleep.
Sleep Regression Quick Comparison (4 vs 6 vs 8 Months)
Feature 4-Month Regression 6-Month Regression 8-Month Regression Primary Cause Permanent change in sleep cycles (brain maturation). Developmental leaps (rolling, sitting) and schedule instability. Separation anxiety and major mobility practice (crawling, pulling up). Nap Schedule Focus Transitioning to a predictable 3-4 nap schedule. Consolidating and protecting the 3-nap schedule. Firmly establishing the 2-nap schedule. Ideal Wake Window Short: 1.5 – 2 hours Medium: 2 – 3 hours Long: 2.5 – 3.5 hours Night Waking Fix Establishing independent sleep (drowsy but awake). Schedule consistency & optimizing daytime calories. Use gentle reassurance to ease separation anxiety.
When to Contact a Pediatrician
Most sleep regressions are completely normal and resolve on their own. However, consult your pediatrician if you notice any of the following red flags [5]:
- Poor growth or feeding issues – your baby isn’t gaining weight or eating adequately.
- Signs of illness – fever, severe congestion, ear pulling, or other concerning symptoms.
- Persistent sleep problems – sleep disruptions last longer than 6 weeks without improvement.
- Extreme fussiness or abnormal behavior – your baby seems unusually irritable or inconsolable.
👉 Crucial Reminder:
If your baby is sleeping poorly but is otherwise happy, feeding well, and does not have a fever, you are most likely dealing with a normal developmental sleep regression. Address the developmental causes (consistency, independent sleep) first. If you spot any of the red flags above, seek medical advice immediately.
Takeaway
The 8-month sleep regression is tough, but it is a positive sign of healthy growth and cognitive development. Disruptions are typically caused by a combination of strong separation anxiety and the baby actively learning new physical milestones, like crawling or pulling up.
To get through this storm, patience and consistency are key. Stick to a predictable bedtime routine, offer gentle reassurance, and create a calm, sleep-friendly environment. These steps will help your baby feel secure and gradually return to more restful sleep.
Frequently Asked Questions (FAQ)
Q1. Does every baby go through an 8-month regression?
Ans. No, some babies skip noticeable regressions, while others show clear disruptions. Most show temporary sleep changes at this age.
Q2. Should I do night feeds during the regression?
Ans. Feed if your baby is genuinely hungry. Try to avoid turning every wake into a full feeding if the baby is only seeking comfort.
Q3. Can sleep training make regressions worse?
Ans. Harsh or inconsistent methods can increase stress. Gentle, consistent sleep training tends to shorten the regression’s impact.
Q4. Will my baby eventually return to normal sleep?
Ans. Yes—most babies return to regular sleep patterns with consistent routines and gentle training. This phase is temporary and developmentally normal.
Q5. Is it the 8 month sleep regression or teething?
Ans. It’s often both. 8 month sleep regression or teething symptoms overlap. The developmental shift is the main cause, but discomfort from teething frequently makes the regression worse. Addressing pain before bed (Step 8) is crucial.
Q6. When does the 8 month sleep regression start and end?
Ans. The regression typically starts between 7 and 9 months and usually lasts between 2 to 6 weeks. Consistency is the fastest way to get through it.
Q7. Why is my 8 month old waking multiple times at night?
Ans. The primary causes are a combination of separation anxiety (realizing you’ve left the room), practicing major developmental milestones (like standing or crawling), and overtiredness from a poor daytime schedule. These factors disrupt the normal sleep cycle, causing them to cry out for you.
