Why Does My Baby Cry in His Sleep? Understanding the Causes and Solutions

Having a baby who cries in their sleep can be concerning for parents. Understanding the possible reasons behind this behavior is important in order to provide comfort and support for your little one.

At what age do babies typically start crying in their sleep?

Babies can start crying in their sleep as early as the first few weeks of life. This is because newborns have immature sleep patterns and may experience discomfort or hunger during the night, leading to crying episodes. As babies grow older, their sleep patterns become more established, and they may cry less frequently during sleep.

It is important to note that every baby is different, and some may start crying in their sleep earlier or later than others. Additionally, the frequency and intensity of crying during sleep can vary from baby to baby.

Factors that may contribute to a baby crying in their sleep:

  • Hunger: Babies have small stomachs and need frequent feeding, so they may wake up hungry during the night and cry for food.
  • Discomfort: Babies may cry if they are too hot or cold, have a wet diaper, or are experiencing any other form of physical discomfort.
  • Overtiredness: When babies become overtired, it can be difficult for them to settle into a deep sleep. This can lead to fussiness and crying during sleep.

Tips for soothing a baby who cries in their sleep:

  1. Check for basic needs: Before assuming that your baby’s crying is due to something more serious, make sure they are not hungry, uncomfortable, or need a diaper change.
  2. Create a soothing bedtime routine: Establishing a consistent bedtime routine can help signal to your baby that it’s time for sleep. This can include activities such as bathing, reading a book, or singing lullabies.
  3. Provide comfort: If your baby wakes up crying during the night, try comforting them by gently rocking or patting their back. You can also offer a pacifier or a favorite blanket or stuffed animal for added comfort.

Common reasons why a baby might cry during sleep

During sleep, babies may cry for various reasons. One common reason is discomfort caused by hunger. Babies have small stomachs and need to eat frequently, so if they are not getting enough nourishment before bedtime, they may wake up crying due to hunger. Another possible cause of crying during sleep is the need for a diaper change. Wet or soiled diapers can be uncomfortable for babies and disrupt their sleep. Additionally, babies may cry in their sleep if they are feeling too hot or cold. Ensuring that the room temperature is appropriate and dressing the baby accordingly can help prevent this discomfort.


Babies have high metabolic rates and need to eat often, especially during their early months. If a baby hasn’t been fed adequately before bedtime, they may wake up crying due to hunger.

Discomfort from wet or soiled diaper

Wet or dirty diapers can be very uncomfortable for babies and disturb their sleep. Checking and changing the baby’s diaper before putting them down to sleep can help prevent this issue.

Inappropriate room temperature

If the room is too hot or too cold, it can make a baby uncomfortable and cause them to cry during sleep. Maintaining an appropriate room temperature by using blankets or adjusting the thermostat can help create a comfortable sleeping environment for the baby.

How long does it usually last when a baby cries in their sleep?

The duration of crying episodes during a baby’s sleep can vary depending on the underlying cause. In some cases, it may only last for a few minutes as the baby transitions between different stages of sleep. However, if the crying persists for longer periods or becomes intense, it could indicate an issue that needs attention.

Normal brief awakenings

Babies naturally cycle through different sleep stages, including periods of light sleep when they may briefly awaken. During these brief awakenings, a baby may cry for a few minutes before settling back to sleep on their own.

Discomfort or hunger

If a baby is experiencing discomfort, such as hunger or a wet diaper, the crying may last until their needs are addressed. This could involve feeding the baby or changing their diaper, which can take several minutes.

Underlying health concerns

In some cases, prolonged crying during sleep may be a sign of an underlying health issue. If the crying continues for an extended period or is accompanied by other symptoms like fever or difficulty breathing, it is important to consult a healthcare professional.

Overall, while some episodes of crying during sleep are normal and resolve quickly, persistent or intense crying should be evaluated further to ensure the baby’s well-being.

Potential health concerns associated with a baby crying in their sleep

Crying during sleep can sometimes indicate potential health concerns in babies. It is important for parents to be aware of these possibilities and seek appropriate medical attention if necessary.

Gastroesophageal reflux (GER)

GER occurs when stomach contents flow back into the esophagus. This condition can cause discomfort and irritability in babies, leading to crying during sleep. Symptoms may include frequent spitting up, coughing, and difficulty feeding. If GER is suspected, parents should consult a pediatrician for proper diagnosis and management.

Ear infections

Ear infections are common among infants and can cause pain and discomfort that worsens when lying down. Babies with ear infections may cry more frequently during sleep due to increased pressure on their ears. Other signs of an ear infection include fever, tugging at the ears, and decreased appetite. A healthcare provider should be consulted for evaluation and treatment if an ear infection is suspected.

Respiratory infections

Respiratory infections, such as colds or bronchiolitis, can make breathing difficult for babies. This can lead to disrupted sleep and increased crying. Symptoms may include coughing, nasal congestion, and rapid breathing. If a respiratory infection is suspected, medical attention should be sought to ensure appropriate management.

It is important for parents to trust their instincts and seek medical advice if they have concerns about their baby’s health or well-being. A healthcare professional can provide proper evaluation and guidance based on the specific circumstances.

Can teething cause a baby to cry in their sleep?

Teething can indeed cause babies to cry during sleep. The process of teeth erupting through the gums can be uncomfortable and painful for infants, leading to increased irritability and disturbed sleep patterns.

Gum inflammation

During teething, the gums become inflamed as the new teeth push through. This inflammation can cause discomfort and soreness for babies, making it harder for them to settle into a peaceful sleep.

Painful gums

As the teeth continue to emerge, they may put pressure on the sensitive nerves in the gums. This pressure can result in varying degrees of pain and discomfort for babies, causing them to cry during sleep.

Disrupted sleep patterns

The discomfort caused by teething can disrupt a baby’s usual sleep patterns. They may wake up more frequently during the night or have difficulty falling back asleep after waking up due to teething-related discomfort.

Parents can help soothe their teething baby by providing appropriate teething toys or rings that are safe for them to chew on. Additionally, using gentle massage techniques on the baby’s gums or applying chilled teething rings can help alleviate some of the pain and discomfort associated with teething.

Is it normal for a baby to cry more frequently at night compared to during the day?

It is common for babies to cry more frequently at night compared to during the day. There are several reasons why this may occur.


During the day, babies are typically more engaged with their surroundings and have various stimuli to keep them occupied. As a result, they may not become as easily fatigued and therefore cry less frequently. However, at night when the environment is quieter and there are fewer distractions, babies may feel more tired and become fussier.

Increased sensitivity

Babies’ sensitivity to external stimuli tends to be heightened at night when the surroundings are darker and quieter. This increased sensitivity can make them more prone to crying as they may be easily startled or disturbed by even minor discomforts.

Developmental changes

Babies go through various developmental milestones, such as growth spurts or leaps in cognitive abilities, which can affect their sleep patterns. These changes can lead to increased crying during sleep as they adjust to new sensations or experiences.

Parents can help manage nighttime crying by establishing consistent bedtime routines and creating a calm sleep environment. Implementing soothing activities like gentle rocking or singing lullabies can also help ease a baby’s transition into sleep.

Strategies parents can use to soothe a crying baby during sleep

When faced with a crying baby during sleep, parents can employ various strategies to help soothe their little one and promote better rest.

Gentle rocking or swaying

Many babies find comfort in gentle movements that mimic being held or rocked. Parents can try softly rocking their baby back and forth in their arms or using a crib that has a gentle rocking motion feature.

White noise or calming sounds

Playing white noise or calming sounds, such as ocean waves or lullabies, can create a soothing environment that helps drown out other noises and promotes relaxation for the baby.

Pacifier use

Offering a pacifier to a crying baby during sleep can provide them with a sense of comfort and help calm their cries. However, it is important to ensure safe pacifier usage and follow any guidelines provided by healthcare professionals.

Gentle touch or massage

Some babies find comfort in gentle touch or massage. Parents can try using soft strokes or light pressure on their baby’s back, arms, or legs to provide a soothing sensation that may help calm them down.

Comfort objects

Introducing a comforting object, such as a soft blanket or stuffed animal (if age-appropriate and safe), can provide a sense of security for the baby during sleep. However, it is important to ensure that these objects do not pose any suffocation hazards.

Parents should remember that each baby is unique, and different strategies may work better for some than others. It may take some trial and error to find the most effective soothing techniques for their individual child.

Signs that indicate if the crying during sleep is due to a nightmare or night terror

Crying during sleep can be caused by various factors, including nightmares and night terrors. Understanding the signs associated with each can help parents differentiate between the two.


Nightmares are vivid dreams that can cause fear, anxiety, and distress in children. When experiencing a nightmare, babies may cry inconsolably upon waking up from their dream. They may also exhibit signs of fear such as clinging to parents or appearing frightened even after they wake up.

Verbal expressions

Babies who have had nightmares might vocalize their distress by whimpering, sobbing, or calling out for their parents during sleep.

Recall upon waking

Older babies who can communicate may be able to recall and describe the content of their nightmares once they wake up. They may express fear of specific objects or situations related to the dream.

Night terrors

Night terrors are episodes of intense fear or agitation that occur during sleep. Unlike nightmares, night terrors typically happen during non-REM sleep and can cause a baby to cry or scream suddenly without fully waking up. The baby may appear confused, unresponsive, and difficult to console during these episodes.

Physical signs

During a night terror episode, babies may exhibit physical signs such as rapid breathing, increased heart rate, sweating, and flushed skin.

Limited recollection

Unlike nightmares, babies usually have little to no recollection of night terrors upon waking up in the morning. They may not remember what caused their distress during the night.

If parents suspect that their baby is experiencing frequent nightmares or night terrors that significantly disrupt their sleep patterns or overall well-being, it is advisable to consult a healthcare professional for further evaluation and guidance.

Differentiating between normal crying and excessive crying during sleep

While some degree of crying during sleep is considered normal for babies, excessive crying could indicate an underlying issue that requires attention. Differentiating between normal crying and excessive crying can help parents determine if further intervention is necessary.

Normal crying

Normal crying during sleep is typically brief and intermittent. It may occur as a natural part of a baby’s sleep-wake cycle or due to minor discomforts like hunger or needing a diaper change. Normal crying does not persist for extended periods and does not significantly impact the baby’s overall well-being.

Brief duration

Normal crying during sleep usually lasts for a few minutes before the baby settles back into sleep on their own.

Resolves with intervention

If the crying is due to hunger or discomfort, it can be resolved by addressing the baby’s needs, such as feeding or changing their diaper.

Excessive crying

Excessive crying during sleep may be characterized by prolonged and intense bouts of crying that are difficult to soothe. It may be accompanied by other symptoms like fever, vomiting, or signs of distress.

Prolonged duration

Excessive crying during sleep can last for extended periods, sometimes exceeding an hour or more, despite attempts to console the baby.

Impact on well-being

Excessive crying can disrupt a baby’s sleep patterns and overall well-being. It may result in poor weight gain, irritability during waking hours, and parental stress.

If parents are concerned about their baby’s excessive crying during sleep or if it is significantly affecting their daily life, they should seek advice from a healthcare professional who can evaluate the situation and provide appropriate guidance.

Does the frequency of crying in a baby’s sleep decrease as they grow older?

The frequency of crying during a baby’s sleep tends to decrease as they grow older and reach different developmental milestones. As babies mature physically and emotionally, they become better equipped to self-soothe and regulate their emotions during sleep.

Newborn stage

Newborns often cry frequently during both awake and asleep periods. Their immature nervous systems make it challenging for them to self-regulate emotions and settle themselves back to sleep easily. Crying is one way newborns communicate their needs for feeding, comfort, or attention.

Infancy stage

As infants develop cognitive abilities and gain more control over their bodies, the frequency of crying during sleep typically decreases. They become better at self-soothing and may require less external intervention to settle back to sleep.

Toddler stage

By the time babies reach the toddler stage, they have usually developed a more robust set of coping mechanisms and emotional regulation skills. This can lead to a further decrease in the frequency of crying during sleep.

While the overall trend is for crying during sleep to decrease as babies grow older, it is important to note that individual differences exist, and some babies may continue to experience episodes of crying during sleep even as they get older. If parents have concerns about their baby’s sleep patterns or excessive crying, it is always advisable to consult with a healthcare professional for guidance and support.

In conclusion, it is important to understand that occasional crying during sleep is a normal part of a baby’s development. However, if the crying becomes excessive or accompanied by other concerning symptoms, it may be necessary to consult with a healthcare professional to ensure the baby’s well-being.
