One of the most common questions new parents ask is, “When does a baby start sleeping through the night?” The answer varies for each child, but generally, most babies start to sleep through the night, which means about six to eight hours at a stretch, between 4 to 6 months of age. Some may take longer to reach this milestone while others might do so sooner.
Understanding Sleep Patterns in Infants
To appreciate when a baby might start sleeping through the night, it’s crucial to understand their sleep patterns and development stages. Newborns need a lot of sleep, usually between 14 to 17 hours over a 24-hour period. However, they have very short sleep cycles, usually lasting 2 to 4 hours, which means they wake up frequently.
Newborn Sleep Cycles
During the first few months, a baby’s sleep is divided into light sleep and deep sleep stages. Newborns spend about half of their sleep time in active sleep, which can be easily disrupted. More frequent feeding, changing diapers, or just needing comfort can wake them up regularly.
The Transition Period
Between 3 to 4 months, babies start to experience longer sleep cycles and less active sleep. It is usually during this period that some babies can begin to sleep for longer stretches at night. This transition does not happen overnight and often involves the baby gradually adjusting to a more extended nighttime sleep period.
Factors That Affect Sleep Through the Night
Several factors contribute to when a baby will start sleeping through the night. These factors include:
Feeding Patterns
Feeding plays a critical role in a baby’s sleep patterns. Newborns have small stomachs and need to be fed frequently. As they grow older and their stomach capacity increases, they can consume more milk or formula at each feeding, helping them to stay full longer and sleep for extended periods.
Developmental Milestones
Every baby grows at their own pace, and developmental milestones can impact sleep. Physical development, such as rolling over, crawling, or even sitting up, can temporarily disrupt sleep as babies may wake up more frequently to practice their new skills. As they become more comfortable and proficient with their milestones, their sleep may stabilize.
Sleep Environment
The environment where the baby sleeps can influence sleep duration and quality. A quiet, dark, and cool room helps promote better sleep. Establishing a consistent bedtime routine helps the baby associate certain activities with sleep time, making it easier for them to fall asleep and stay asleep longer.
Parental Influence
Parents can significantly impact when their baby begins to sleep through the night through their responses and routines. Here’s how:
Establishing a Bedtime Routine
A consistent bedtime routine is one of the most effective strategies to help your baby sleep through the night. Activities such as a warm bath, reading a story, or gentle rocking can signal to your baby that it’s time to sleep. Consistency is key; adopting the same routine every night helps your baby understand and anticipate sleep.
Responding to Night Wakes
How parents respond to night wakes can also affect sleep patterns. While it’s essential to attend to your baby’s needs, providing minimal stimulation during night wakings, such as avoiding bright lights and loud sounds, helps signal to the baby that nighttime is for sleeping.
Recognizing Signs of Readiness
Each baby shows different signs indicating they might be ready to start sleeping through the night. These signs include:
Increased Nighttime Sleep
If your baby begins to sleep for most of the night and wakes less frequently for feeding, it could mean they are ready to transition to sleeping through the night.
Longer Daytime Awake Periods
Babies who stay awake for more extended periods during the day usually start consolidating their sleep at night. This shift helps them to sleep longer stretches at night.

7% OffSelf-Soothing Abilities
Babies who can self-soothe, like sucking on their thumb or a pacifier or finding ways to calm down, are more likely to sleep through the night. Teaching self-soothing is an essential part of sleep training.
Sleep Training Methods
Sleep training can be a helpful approach for parents seeking to encourage their baby to sleep through the night. Various methods cater to different parenting styles and the baby’s temperament. Some common sleep training methods include:
Cry-It-Out (CIO)
The Cry-It-Out method involves letting the baby cry for a specified period before comforting them. The intervals of crying may gradually increase over time. This method teaches the baby to self-soothe and fall asleep independently.
Ferber Method
The Ferber Method is a modified CIO approach involving incremental periods of waiting before comforting the baby. Parents gradually extend the waiting time, helping the baby to learn to self-soothe while still receiving intermittent comfort.
Gentle Sleep Training
This method involves a gentler approach with consistent routines and subtle changes to gradually encourage the baby to sleep through the night. It may include techniques like “the fading method,” where parents slowly reduce their presence over time, allowing the baby to adjust at a slower pace.
Common Challenges and Solutions
While aiming for a baby to sleep through the night, parents may encounter common challenges. Here’s how to tackle them:
Frequent Night Wakings
If your baby wakes frequently, evaluate their sleep environment, feeding schedule, and any potential discomforts (like teething). Ensuring a comfortable and consistent bedtime routine can help reduce night wakings.
Sleeping at Different Times
Irregular sleep patterns can make it difficult for a baby to sleep through the night. Try to maintain regular nap and bedtime schedules to encourage better nighttime sleep.
Separation Anxiety
As babies grow, some may experience separation anxiety, making it harder for them to sleep through the night. Providing reassurance through a consistent bedtime routine and gentle comfort can help alleviate this anxiety.
Monitoring and Adjusting
Monitoring a baby’s sleep progress and being open to adjustments can make achieving nighttime sleep more manageable. Keep a sleep journal to track patterns, making it easier to spot trends or issues that may need addressing.
Seek Professional Advice
If sleep challenges persist, consulting with a pediatrician or sleep specialist can provide insights tailored to your baby’s specific needs. Professional guidance can help address underlying issues and offer personalized solutions.
Patience and Flexibility
Every baby is unique, and sleep patterns can vary. Patience and flexibility are essential. Understand that it’s normal for babies to have fluctuations in their sleep schedules, and sometimes minor adjustments can make a significant difference.
Finishing Thoughts
In summary, most babies begin to sleep through the night between 4 to 6 months of age; however, this timeline can vary widely. Understanding infant sleep patterns, establishing consistent routines, and being mindful of different factors impacting sleep are essential steps in helping your baby achieve this milestone. Patience, consistent bedtime routines, and knowing when to seek professional advice can all contribute to ensuring your baby, and you, get a good night’s sleep.
