Why Do Babies Cry In Their Sleep? Top Full Guide 2022

  • Repopny

There are a few reasons why babies cry in their sleep. They may be having a bad dream, or they may be experiencing some discomfort. It’s also possible that they’re simply missing their parents and are feeling lonely.

In this article, Repopny will find the answer to the question: why do babies cry in their sleep? And how to comfort your baby and let them know that you’re there for them.

What Causes Babies To Cry While Sleeping?

Although it is unusual for babies to cry while sleeping, it does occur. When some parents hear their infant wailing, they turn on the monitor only to find their baby’s eyes closed. Other parents may check on their child only to discover that the wailing has stopped and that their child is sound asleep.

You may be perplexed by this behavior and wonder whether something is wrong. Understanding why newborns scream in their sleep will assist you in determining what to look for and how to help your child.

Weeping as you switch from one sleep cycle to the next

Babies, like adults, sleep in cycles. Unlike adults, however, babies switch between sleep cycles quickly and spend more time in REM sleep than deep sleep.

You may observe your baby’s eyes moving a lot under their eyelids during this stage (this is where the term “rapid eye movement,” or REM, comes from). During REM sleep, babies can be seen moving their arms and legs, closing and opening their hands, twitching or jerking, and even wailing.

Many babies will experience a brief waking at the end of each cycle, which lasts 40 minutes. Babies may wail for a few minutes before returning to sleep, or they may not even wholly awaken during this brief wakeup.

What Causes Babies To Cry While Sleeping

Crying as a result of exhaustion

Babies can quickly become overtired if they don’t get enough sleep or are awake for longer than they can handle. Overtiredness causes fatigue-fighting chemicals to be released, making it more difficult for babies to fall and remain asleep.

It appears to be counter-intuitive, and it cannot be easy. The most typical causes of your infant weeping in their sleep are exhaustion and large tears soon before falling asleep.

Teething pain causes crying

When dental buds start to emerge, babies may be irritated – and they’ll let you know. Teething babies are fussier and will frequently whine throughout the day and night owing to the discomfort.

You may observe more frequent mild sobbing or whimpering while your kid is asleep if you feel they are working on a new tooth. Inquire with your child’s pediatrician about treatment options for teething pain.

When your baby is crying in their sleep, it’s good to wait and watch unless you’re concerned about their safety. When you react too hastily, you risk waking your child up completely or preventing them from falling back asleep on their own.

Crying during sleep is developmentally acceptable and does not always necessitate assistance. So, the next time your kid starts sobbing with their eyes closed, take a step back and wait to watch what happens. Your kid may astound you by ceasing to cry on their own!

Is It Possible For Babies To Have Nightmares?

“What are they dreaming about?” we’ve pondered as we watch our newborns sleeping. Those beautiful smiles your kid gives in their sleep are involuntary and not in response to a dream (but we can all dream, right?).

Dreaming begins later in life, around the age of two. What’s the good news? Babies do not have nightmares, night terrors, or horrible dreams, and weeping in their sleep is most likely due to the causes above.

How Can You Calm A Crying Baby?

When a baby cries out momentarily in its sleep, it usually settles down on its own. Picking them up may wake them up, causing sleep disruption.

If the crying persists, try quietly speaking to the baby or gently massaging their back or stomach. This can help them transition to a different sleep stage and cease screaming.

Breastfed newborns who suckle while sleeping may find nursing comforting. Caregivers should consider if the infant will wake up from nursing and whether they are prepared to take the risk of waking the baby.

Observing the baby’s sleep habits might also be beneficial. Some babies cry quietly as they drift off to sleep or just before waking up. Caregivers can analyze the cause of weeping by identifying the baby’s regular sleep cycle.

When a baby is unwell or teething, they may cry in their sleeping, but the pain that causes crying usually wakes the baby up. Caregivers can consult a pediatrician for advice on alleviating the baby’s discomfort.

How Can You Calm A Crying Baby

Although we don’t know when dreams begin, a caregiver who suspects their child is suffering might quiet them down by talking calmly or caressing their back. Nursing may provide comfort to babies who are still breastfed.

If a baby wakes up after a nightmare, console them and put them back to sleep with a calming sleep ritual. Older newborns and toddlers may require reassurance that the experience was merely a nightmare.

When Should You Consult A Doctor?

  • Talk to your doctor about nighttime crying or other problems.

  • A child’s sleeping habits can suddenly change
  • This problem can last several nights and cause sleep problems in children. It interferes with caregivers’ ability to function.
