Baby Sighing During Sleep – Exploring The Reason Why

Baby SighingAlthough babies are entirely human, this may not always seem to be the case. Their behaviors are awkward at times and this makes it incredibly difficult for new parents to fully understand their toddler.

Of course, there is a rhyme and reason for every little odd behavior that your child exhibits. This is true, when it comes to your baby sighing during his or her sleep. Why do they do it? Within this guide, you’ll be able to find out.



A Misconception And Unwarranted Fear

Most people will quickly associate a sigh with sadness or distress. In an adult, this could very well be the case. Adults can sigh for a handful of different reasons, including exhausting, sadness and distress.

In a baby, this is entirely different. Therefore, if your baby begins sighing, while they sleep, you shouldn’t worry. Your baby isn’t in any sort of distress. Just take a deep breath and continue reading, so you can better understand your child’s sigh.



A Baby’s Sleeping Sigh 

These quick research studies have concluded that this behavior can play a role in the baby’s development.

So, what precisely does a baby’s sign tell you? Well, it is very common for babies to sigh, while they sleep, and it is actually natural. In fact, it isn’t the baby performing the action at all. Instead, the baby’s body is initiating the response, while telling you that their body is behaving in the appropriate manner. In babies, this is actually a good thing and will let you know that everything is entirely fine.

As for the reasons babies sigh, they’re plentiful, but none have been proven indefinitely. Instead, there have been a handful of studies, which have tried to pinpoint the cause. Below, you will be able to discover some of the main reasons for a baby to sigh during their sleep and how the behavior might be linked to the baby’s development.



Developing Lungs

When your baby is first born, he or she will not have fully developed lungs. Instead, it takes a period of time, before this vital organ is developed to the maximum state. Some research has shown that the sighing could very well point to the development of the child’s lungs.

The sighing helps to open the baby’s airways, which in return gives him or her the ability to obtain more oxygen. This helps to support and make the lungs more efficient, until the baby’s lungs have fully developed.

Regulating Breathing

On the other hand, the sighing could very well be the body’s way of regulating the child’s breathing. This minute action could stimulate the child’s short-term memory, while giving them the ability to better establish a more harmonic breathing pattern.

Also, the child’s sigh could help the body space out their breathing to a more efficient duration. Finally, this action could help the child better acclimate to sounds and movements, which are produced during the course of their slumber.



Enhancing The Autonomic Nervous System

The body’s autonomic nervous system, or ANS, is responsible for managing and regulating many of the body’s most essential organs, including the digestive system and the heart. The ANS also takes on the duty of controlling the body’s glands and muscles. During the baby’s sleeping, it is believed that the sigh helps to stimulate the ANS and make it work more efficiently.

Also, when the child falls asleep, they’re actually rebooting their autonomic nervous system and giving it the ability to start fresh. This is truly vital, since a malfunctioning ANS can result in a variety of problems, including respiratory organ and heart disorders.

With this in mind, the sigh is not only normal, but also it is considered by many to be crucial for the child’s overall health.



Other Things To Know About The Baby’s Sigh

Truthfully, the human body is a masterpiece and a wonderful mystery. Despite using and researching the human body for many centuries, many questions remain. Some babies will actually sigh more than others and this is especially true, when it comes to pre-term children.

In order to fully understand your child’s sighing, you need to familiarize yourself with Rapid Eye Movement, or REM. This type of sleep is very common amongst babies and it refers to sleep with a major increase in the child’s brain stimulation. During this type of sleep, the child will appear to be very active, despite snoozing soundly.

Also, you should know about the apneic pause. This is a short duration of time during regular breathing when airflow is put to a short halt. When the child has entered the REM sleeping stage, they’ll sigh without the apnea pause. This is the exact opposite, if the child has entered the non-REM sleeping cycle.



Better Understanding Your Child’s Sleeping Patterns

Newborns and babies, in general, can go through patterns, in which their sleeping schedule is erratic. In order to ensure that your child obtains a sufficient amount of sleep, it is essential to learn about the most common baby sleeping patterns and facts. Some of these will be listed below.


  • Again, newborns can go through erratic and awkward sleeping patterns. Sometimes, they’ll sleep 18 hours a day. Other times, they may doze off for a little over 10 hours. As the baby begins to grow, they’ll sleep a little less. Those over 3 months of age will generally obtain 9 to 12 hours a day. Of course, the real trick is the fact that this sleep is rarely obtained in a single session.
  • Although there are some guidelines, the truth of the matter is that each baby is entirely unique. Their patterns, preferences and requirements can differ substantially. With this in mind, it is sometimes best to allow the child to dictate and establish his or her own sleeping rhythm and schedule. Although it is possible to manipulate the schedule to some degree, you should attempt to work close with your child’s natural schedule as much as possible.
  • Finally, you should know that your child’s growth and development could be directly impacted by their sleeping patterns.



Good Sleep Is Essential For Good Health

Last, but certainly not least, you should understand that your child’s sleeping behavior can negatively or positively impact their mental and physical development. When you hear your child sigh, during his or her sleep, you should simply put a smile on your face.

A sigh is truly a good thing and can help you confirm that your child is sleeping restfully. Familiarize yourself with your child’s sleeping patterns and preferences, so you can easily identify any problems that may occur.

    Hi. Thanks very much for your Page. Im really worried about my 2 months old baby. He sighs a lot while sleeping. After every sigh, he stops breathing for about 7 secs. What do you think about this?

      It’s hard to say Berta, you really need to talk to your doctor about this since it could be sleep apnea and needs to be treated.
