Baby Sleep Noises

Causes of Baby Sleep Noises/Sound

There are various reasons for baby sleep noises:

1. Continuous Growth

After birth, the baby is not accustomed to the outside environment and struggles to adjust to the external world. A lot of continuous developments and changes happen in the infant’s body throughout the day and night. And the respiratory organs and digestive system often adjust to the situation, creating some awkward sounds.

2. Irregular Sleeping Cycle Leads to Baby Sleep Noises

According to, depending on the age of the baby, the sleeping pattern changes. Newborns are very much sleepy, but this sleep is not a continuous and long one. The periods of sleep are very short, and babies constantly move and out of their sleep causing different sounds which are pretty normal. They turn frequently, might dream and smile during sleep, make sucking sounds as if they are always in hunger.

3. REM (Rapid Eye Movement) Sleep

Generally, the sleeping style of babies is different from that of adults. According to a study done by, they have a REM (Rapid Eye Movement) sleep most of the time which is a condition of dream time sleep with a shorter duration . This is also called a night of active sleep. The newborn moves a lot with the flow of the dream, and this is quite noisy.

4. Baby Sleep Noises Due to Small Nostrils

Babies predominantly breathe through their nostrils which are very small. When air passes through those tiny holes, it makes a whistling sound. Don’t worry about it, it’s normal.

Newborn Breathing Sounds

Generally, parents are worried about the different types of breathing sounds they hear during baby sleep time. But these sounds are most common and normal. As the baby’s lungs mature with time, the irregular breathing sound disappears.

Below are some normal breathing sounds of a newborn:

1. Normal Periodic Breathing

A slow shallow sound can be heard during the periodic breathing of your baby and this is normal. In this kind of breathing pattern, there is a short pause of 8 to 10 seconds. After the first 2 months of life, this issue gets resolved.

2. Rapid Breathing

Typically, there are 30 to 60 breaths per minute for a newborn and it can be slowed down to 20 times during their sleep. But sometimes they inhale a lot of air one time and then the respiration pattern comes down to normal. During the initial period of birth, the overall system of the newborn’s body is trying to synchronize altogether, and this causes this type of sound. This may last for some minutes only.

3. See-Saw Breathing

Variations in respiratory patterns are observed during the first few weeks of a newborn. Rapid fluctuating rates of respiration and variable rhythms in this period are often termed as “see-saw breathing”. This happens due to the shifting of one pattern to another.

Besides these, some of the other breathing sounds you can hear are:

4. Whistling

As babies predominantly are nose-breathers, the airflow through their narrow nasal passage makes this kind of sound.

5. Gurgling

Due to a pool of saliva at the backside of the mouth, this type of sound is generated.

6. Hiccups

This is very strong in infants. Even before their birth, you can feel the same. Not a point of concern, you can do burping, and rub the back of your baby but generally, babies resolve it on their own.

7. Snoring

Particularly during sleep, the extra mucus or dryness causes this kind of sound. Generally, these sounds are not a cause of worry.

Newborn Digestive Sounds

The digestive system of a newborn is in the developing stage. They are in a hungry mood throughout the day and night and soiling their diapers frequently. Therefore, some strange sounds are often observed. Some of the common digestive sounds of infants are:

  • Belching
  • Burping
  • Churning
  • Growling
  • Grunting
  • Gurgling
  • Hiccups
  • Passing gas
