Why Does My Baby Cry in Her Sleep? Understanding the Causes and Solutions for Restless Nights

Baffled by your baby’s nighttime cries? Discover the reasons behind why your little one may be crying in their sleep and find helpful solutions to ensure a peaceful night for both of you.

1. At what age do babies start crying in their sleep?

Most babies start crying in their sleep around 2 to 3 weeks of age. This is a normal part of their development and is often referred to as “sleep-crying.” It is believed that this crying occurs during the REM (rapid eye movement) phase of sleep, which is when dreams occur. During this phase, babies may make various sounds, including whimpers, cries, and even laughter.

It’s important to note that not all babies cry in their sleep, and the frequency and intensity of sleep-crying can vary from baby to baby. Some babies may cry for a few seconds or minutes before settling back into a deep sleep, while others may cry for longer periods or even wake up fully.


Overall, it is considered normal for babies to cry in their sleep during the first few months of life. However, if your baby’s crying becomes excessive or is accompanied by other concerning symptoms, it’s always a good idea to consult with your pediatrician.

2. Is it normal for babies to cry in their sleep?

Yes, it is completely normal for babies to cry in their sleep. As mentioned earlier, this phenomenon is known as “sleep-crying” and typically starts around 2 to 3 weeks of age. Sleep-crying is believed to be a result of the brain processing information and emotions during the REM phase of sleep.

Babies may cry in their sleep for various reasons. It could be due to hunger if they haven’t been fed recently or discomfort from gas or colic. They may also cry if they are too hot or cold or if they need a diaper change. Sometimes babies may simply be experiencing an emotional release during their dreams.

If your baby cries in their sleep, it’s important to assess their overall well-being. If they are otherwise healthy, gaining weight appropriately, and have no other concerning symptoms, there is usually no cause for alarm. However, if you have any concerns or if the crying becomes excessive or accompanied by other worrisome signs, it’s always best to consult with your pediatrician.

3. What are the possible reasons why a baby cries in her sleep?

Babies can cry in their sleep for various reasons. Here are some common factors that may contribute to sleep-crying:

1. Hunger:

If your baby is not getting enough milk or formula during the day, they may wake up hungry and cry during their sleep. It’s important to make sure your baby is adequately fed before putting them down for the night.

2. Discomfort:

Babies may cry in their sleep if they are uncomfortable due to gas, colic, teething pain, or an illness such as an ear infection. Checking for signs of discomfort and addressing any underlying issues can help alleviate sleep-crying.

3. Temperature:

If your baby is too hot or too cold while sleeping, they may cry as a way of signaling their discomfort. Ensure that your baby’s sleeping environment is at a comfortable temperature and dress them appropriately for the weather.

4. Dreams and Emotional Release:

Babies experience dreams just like adults do during the REM phase of sleep. These dreams can evoke emotions that result in crying or fussing. It’s believed that this crying helps babies process emotions and experiences.

It’s important to note that every baby is unique, and the reasons for sleep-crying can vary from one child to another. Understanding your baby’s individual needs and cues can help you better address their sleep-crying episodes.

4. How can I differentiate between normal sleep crying and something more serious?

It is common for babies to cry in their sleep, but it is important for parents to be able to distinguish between normal sleep crying and signs of a more serious issue. One way to differentiate is by observing the baby’s behavior during the day. If the baby is generally happy, alert, and meeting developmental milestones, then the sleep crying is likely normal. However, if the baby shows other symptoms such as fever, difficulty breathing, or unusual irritability during waking hours, it may indicate a medical condition that requires attention.

Another factor to consider is the duration and intensity of the crying. Normal sleep crying usually lasts for a few minutes and gradually subsides on its own. On the other hand, if the crying persists for an extended period of time or becomes increasingly intense, it may be a sign of discomfort or pain that needs further investigation.

5. Are there any specific signs or cues that indicate why a baby is crying in her sleep?

While it can be challenging to determine exactly why a baby is crying in her sleep without waking her up, there are some cues that parents can look out for. One common reason for sleep crying is hunger. If the baby has not been fed recently or has been going through a growth spurt, she may wake up and cry due to hunger.

Another possible reason for sleep crying could be discomfort from wetness or soiled diapers. Babies have sensitive skin and may become agitated when they feel wet or dirty during their sleep. Checking and changing their diaper before bedtime can help prevent this issue.

List of possible reasons for sleep crying:

  • Hunger
  • Discomfort from wet/dirty diapers
  • Need for burping
  • Temperature changes
  • Overstimulation during the day
  • Colic or digestive issues

6. Can teething cause a baby to cry in her sleep?

Yes, teething can be a common cause of sleep crying in babies. The discomfort and pain associated with teething can disrupt their sleep and lead to crying episodes. During the teething process, babies’ gums become swollen and tender, causing them discomfort. This discomfort is often more prominent at night when they are lying down and not distracted by other activities.

If you suspect that your baby’s sleep crying is due to teething, there are several strategies you can try to soothe them. Providing a chilled teething toy or gently massaging their gums with a clean finger can help alleviate their discomfort. Additionally, offering them cool water or using over-the-counter teething gels may also provide relief.

7. Are there any common medical conditions that may make a baby cry during sleep?

While most instances of sleep crying in babies are harmless and normal, there are some medical conditions that can cause increased crying during sleep. One such condition is gastroesophageal reflux (GER), where stomach acid flows back into the esophagus, causing irritation and discomfort.

Sleep apnea is another medical condition that may contribute to increased crying during sleep. Sleep apnea occurs when a baby’s breathing is temporarily interrupted while sleeping, leading to fragmented sleep patterns and irritability.

List of common medical conditions:

  • Gastroesophageal reflux (GER)
  • Sleep apnea
  • Allergies or sinus issues
  • Ear infections
  • Respiratory infections
  • Urinary tract infections (UTIs)

8. How can I soothe my baby if she wakes up crying during the night?

Using gentle touch and comforting techniques

If your baby wakes up crying during the night, there are several soothing techniques you can try to help calm her down. One effective method is using gentle touch, such as stroking her back or gently patting her bottom. This physical contact can provide a sense of security and comfort, helping your baby relax and fall back asleep.

In addition to touch, you can also try other comforting techniques like rocking or swaying your baby gently in your arms. The rhythmic motion mimics the feeling of being in the womb and can have a calming effect on your little one.

Tips for creating a soothing sleep environment

  • Ensure the room temperature is comfortable – not too hot or cold.
  • Use a white noise machine or soft music to create a peaceful atmosphere.
  • Consider using a nightlight or dim lighting to provide a sense of security.
  • Create a consistent bedtime routine that includes calming activities like reading or singing lullabies.

9. Is it necessary to intervene when a baby cries in her sleep, or should I let her self-soothe?

The decision to intervene when your baby cries in her sleep depends on various factors, including your parenting style and your baby’s age and temperament. Some parents prefer to let their babies self-soothe and learn how to fall back asleep independently, while others may choose to offer comfort and reassurance immediately.

The benefits of allowing self-soothing

Letting your baby self-soothe can encourage healthy sleep habits and promote independent sleep. It can teach your little one how to soothe herself back to sleep, which is an essential skill for her overall sleep development. Self-soothing can also help reduce dependency on external soothing methods, such as rocking or feeding.

When to intervene

However, it’s important to consider your baby’s age and needs when deciding whether to intervene or let her self-soothe. Newborns and young infants may require more immediate attention and comfort during nighttime awakenings. As babies grow older and develop better self-soothing skills, you can gradually encourage them to settle themselves back to sleep without intervention.

10. Will my baby outgrow this phase of crying during sleep, or is it something that may persist?

The phase of crying during sleep is a common occurrence in babies, but the duration and persistence can vary from child to child. While some babies may outgrow this phase relatively quickly, others may continue experiencing night-time crying for a more extended period.

Factors influencing the duration of crying during sleep

Several factors can influence how long this phase lasts. One factor is your baby’s temperament – some babies naturally have a more sensitive disposition and may take longer to adjust their sleep patterns. Additionally, changes in routine or developmental milestones like teething or growth spurts can temporarily disrupt your baby’s sleep and lead to increased night-time crying.

Tips for managing night-time crying

  • Stick to a consistent bedtime routine to provide predictability and security for your baby.
  • Ensure that your baby’s basic needs are met before bedtime – she should be well-fed, dry, and comfortable.
  • Offer comforting techniques like gentle touch or soothing sounds if your baby wakes up crying.
  • Be patient and understanding during this phase, as it is a normal part of your baby’s sleep development.

In conclusion, babies may cry in their sleep due to a variety of reasons including hunger, discomfort, or the normal development of their sleep patterns. It is important for parents to observe and understand their baby’s individual needs in order to provide appropriate care and comfort.

Why do babies suddenly cry in their sleep?

Infants and young babies often make grunting, crying, or screaming noises while asleep. Because their bodies are still adjusting to a regular sleep cycle, it is normal for them to wake up frequently or produce unusual sounds during sleep. For infants, crying is their primary way of expressing themselves.

Do babies have bad dreams when they cry in their sleep?

If your baby is experiencing intense crying and screaming while asleep, you can wake them up from a nightmare. Once they are awake, it is recommended to sit with them and provide reassurance until they are calm.

What is a sobbing spasm?

Sobbing is a natural response that happens when the diaphragm spasms and the glottis closes, causing a distinct sound.

How do I know if my baby is having night terrors?

Night terrors often exhibit the following traits: your child experiences fear but cannot be woken up or pacified, their eyes are open yet they are unaware of your presence, and the episode typically lasts anywhere from 10 to 30 minutes.

How do I know if my baby is crying in his sleep?

During this phase, you may observe your infant’s eyes moving frequently beneath their eyelids, which is referred to as “rapid eye movement” or REM. Babies may also move their limbs, open and close their hands, twitch or jerk, and even cry while in REM sleep.

At what age do night terrors start?

Night terrors are not very common, occurring only in 3% to 6% of children, whereas nightmares can happen to almost every child from time to time. Typically, night terrors occur in children aged 4 to 12, but there have been instances reported in babies as young as 18 months.
