At 8 months old, your baby is experiencing rapid growth and development, which can significantly affect their sleep patterns. While many babies start to sleep for longer stretches at night, they may still wake frequently due to discomfort from teething, hunger, or new physical milestones like sitting up or crawling. As your baby becomes more aware of their surroundings, their sleep can be easily disrupted by external stimuli, such as light or noise, making this an important time for developing healthy sleep habits.
Understanding these changes and challenges can help you support your baby’s sleep needs effectively. Establishing a consistent bedtime routine, managing discomfort, and creating a calm, safe sleep environment can ease nighttime disruptions. By recognizing and addressing the factors that impact their sleep, you can ensure both you and your baby enjoy restful, rejuvenating nights.
Understanding the Sleep Cycle of an 8 Month Old

By the time your baby reaches 8 months, their sleep cycle is becoming more similar to that of an adult, though it is still shorter. An 8 month old typically experiences sleep cycles that last about 45 to 60 minutes, which consist of lighter sleep stages and deeper, more restorative sleep. Unlike adults, babies tend to spend more time in lighter sleep, which means they may wake up between cycles. This is why many 8-month-olds experience brief wake-ups throughout the night.
During deep sleep, your baby’s body is resting and growing, and their brain is consolidating memories and skills learned during the day. However, because babies’ sleep cycles are shorter, they may rouse more easily when transitioning between light and deep sleep phases. This is a common cause of night wakings, but over time, your baby will begin to transition more smoothly between cycles as their sleep patterns mature.
How Much Sleep Does an 8 Month Old Need?
At 8 months, your baby will typically need between 12 and 14 hours of sleep in a 24-hour period. This includes both nighttime sleep and daytime naps. On average, 8-month olds sleep about 10 to 12 hours at night, with one or two brief wake-ups, often related to hunger, teething, or separation anxiety. During the day, they usually take two naps, each lasting 1 to 2 hours.
It's important to remember that every baby is different, so while some babies may sleep more soundly, others might need a bit more time to settle down. Establishing a consistent bedtime routine and sleep environment can help your baby get the sleep they need, even if they are still waking up during the night.
Developmental Milestones at 8 Months and Their Impact on Sleep
The 8 month mark is a time of exciting milestones. Your baby may be crawling, pulling themselves up to stand, and exploring their world in new ways. These developmental milestones can affect your baby’s sleep in several ways. For instance, your baby might be so excited about their new skills that they become overstimulated or overactive just before bedtime, making it harder for them to wind down. Additionally, their growing sense of independence can trigger separation anxiety, which may cause them to feel more unsettled at night, leading to more frequent wake-ups.
Teething is another common developmental hurdle at this age. As the first set of teeth begin to break through, your baby may experience discomfort that disrupts their sleep. While teething pain can make falling asleep or staying asleep more difficult, offering teething toys or a cold washcloth to chew on can help soothe sore gums before bedtime.
Typical Sleep Schedule for an 8 Month Old

By 8 months, your baby’s sleep schedule is becoming more predictable. A typical day might look something like this:
Morning Wake-Up
Around 6:30 to 7:00 AM, followed by a morning feeding and some playtime. This is usually the time when your baby is most alert and ready for interaction. During this early part of the day, your baby is full of energy and curiosity, making it an ideal time for bonding activities like tummy time, singing, or reading to stimulate their development.
First Nap
About 2 to 3 hours after waking, typically around 9:30 or 10:00 AM, and lasting 1.5 to 2 hours. At this point, your baby will be ready for a rest after a busy morning of exploring. If you notice your baby starting to show signs of tiredness—like rubbing their eyes or getting fussy—this is a great time to start the wind-down routine to help them settle for their nap.
Second Nap
After a few hours of wakefulness, your baby may take a second nap around 2:00 or 3:00 PM, lasting another 1.5 to 2 hours. By this time, your baby may be feeling a bit more energetic again, so it’s important to keep the environment calm and quiet to encourage a peaceful nap. A darkened room and soothing sounds can help your baby fall into a restful sleep for the afternoon.
Bedtime
A consistent bedtime routine can signal to your baby that it’s time to sleep for the night. This usually occurs around 7:00 or 7:30 PM, allowing for a solid stretch of sleep before the next morning. Establishing a soothing routine, such as a warm bath, a lullaby, or reading a favorite book, helps signal to your baby that bedtime is approaching, making it easier for them to wind down and settle into a restful night of sleep.
While this schedule can serve as a helpful guideline, be flexible based on your baby’s unique sleep cues. If your baby seems tired earlier or later than expected, adjust the schedule accordingly. Each baby has their own rhythm, and being responsive to their needs will help you maintain a consistent and supportive sleep routine.
Why Does My 8-Month Old Wake Up at Night?
It’s common for 8 month olds to wake up during the night, even if they were previously sleeping soundly. There are several reasons for this:
- Teething Discomfort: As your baby’s teeth start to emerge, it can cause discomfort and disrupt their ability to stay asleep. Teething can cause pain, drooling, and irritability, leading to nighttime wake-ups.
- Separation Anxiety: Around 8 months, babies often experience separation anxiety. They may wake up during the night and cry out for comfort because they miss their caregiver’s presence.
- Developmental Growth Spurts: The rapid development happening at this age—whether it’s new physical skills like crawling or cognitive milestones—can cause some sleep disruptions. Your baby’s brain is processing all the new information, which can affect their ability to stay in a deep sleep.
- Sleep Regression: Your baby may experience a sleep regression, where they temporarily start waking more frequently or struggle to fall asleep independently.
If night wakings become frequent, it’s essential to stay consistent with your sleep routine. Gentle techniques like allowing your baby to self-soothe, offering comfort without picking them up immediately, or providing a comfort object like a soft blanket can help ease night wakings.
Sleep Training Techniques for 8 Month Olds
Sleep training at 8 months can be a helpful way to encourage your baby to fall asleep independently. However, it's important to be patient, as babies at this age are still learning to self-soothe. Sleep training methods such as the Ferber method (gradual check-ins) or the Chair Method (gradually reducing your presence) can be effective in helping your baby learn to settle down at bedtime.
If you haven’t already introduced a bedtime routine, now is a great time to establish one. Consistency is key—whether it’s a warm bath, quiet time, or a lullaby, a predictable routine signals to your baby that it’s time to sleep. If your baby is particularly anxious, consider a more gradual approach to sleep training, where you slowly reduce your involvement as they become more comfortable with self-soothing.
Tips for Encouraging Better Sleep Habits
- Create a Consistent Bedtime Routine: A consistent and calming routine, such as a warm bath, reading a short book, and a final feeding, can help signal to your baby that it’s time for bed.
- Establish a Safe Sleep Environment: Make sure your baby’s crib is free from loose blankets, pillows, and stuffed animals to prevent any safety risks. Keep the room dark, quiet, and at a comfortable temperature to encourage rest.
- Encourage Independent Sleep: If you haven't already, try laying your baby down in their crib when they are drowsy but still awake. This can help them learn to fall asleep independently.
- Limit Naps Late in the Day: While 2 naps are typical at this stage, avoid letting your baby nap too late in the afternoon, as this can interfere with their bedtime.
By being patient and consistent, you’ll help your baby develop good sleep habits that will benefit them in the months ahead.
When to Seek Professional Advice
If your 8-month-old continues to have significant sleep difficulties, such as prolonged night wakings, excessive fussiness, or difficulty settling into sleep, it may be time to consult with your pediatrician. Sleep issues can sometimes be linked to underlying conditions such as reflux, allergies, or sleep apnea.
Additionally, if you notice any unusual changes in your baby’s feeding or overall behavior, it’s always a good idea to check in with your healthcare provider to rule out any medical concerns.
What to Expect in the Coming Months
As your baby approaches their first birthday, expect their sleep patterns to become even more predictable. Many babies at this age are able to sleep 10 to 12 hours overnight with fewer nighttime awakenings, and their naps may consolidate into one longer afternoon nap. The sleep challenges you face at 8 months will eventually give way to more stable routines, but be prepared for the occasional disruption as your baby reaches new milestones.
Conclusion
Your 8 month old’s sleep journey is a dynamic and evolving process, shaped by developmental milestones, teething, and natural changes in their sleep cycles. At this stage, your baby typically needs around 12 to 14 hours of sleep, divided between nighttime rest and daytime naps.
Understanding your baby’s sleep patterns, recognizing developmental milestones, and being prepared for the occasional sleep disruption will help you navigate this stage with confidence. Consistency, patience, and a gentle approach to sleep training will go a long way in ensuring that both you and your baby enjoy restful nights and joyful days.
