Newborns often move around, grunt, and make noises in their sleep, which can be surprising for new parents. This is normal and usually occurs because newborns spend about 50% of their sleep time in the REM stage, which is characterised by increased brain activity and heightened muscle movement. Newborns also have shorter and more active sleep cycles than older children and adults, resulting in more movements and sounds. This behaviour usually decreases as babies grow and their bodies mature.

What You'll Learn
Newborns' nervous systems are underdeveloped
Newborns spend about half of their sleep time in the REM (rapid eye movement) stage, which is characterised by increased brain activity and heightened muscle movement. This can include twitches, squirms, and even brief vocalisations like crying or moaning. Their nervous systems are underdeveloped, and they are still adjusting to their new environment outside the womb, so their bodies are learning how to function properly.
Newborns' sleep cycles are shorter and more active than those of older children and adults, resulting in more movements and sounds. Their nervous systems are immature, and they are still developing the ability to regulate their breathing and heart rate. As a result, newborns may squirm and grunt in their sleep as they adjust to breathing outside the womb. They are also learning how to use their digestive systems, which can cause discomfort and noise as they adjust to digesting milk. In addition, newborns may experience acid reflux or gastroesophageal reflux (GER), where stomach contents flow back into the oesophagus, which can be uncomfortable and cause them to grunt or squirm.
Newborns may also squirm in their sleep due to overstimulation or overtiredness. Establishing a consistent bedtime routine can help signal to the baby when it is time to transition to sleep. Creating a calm, quiet environment with soft music or white noise can also help soothe and comfort the baby. It is important to pay attention to the baby's cues, such as rubbing their eyes or pulling their ear, which may indicate that they are overtired.
In most cases, newborn squirming and grunting in their sleep is normal and not something to worry about. However, if the behaviour seems excessive or is accompanied by other symptoms, it is best to consult a doctor or paediatrician to rule out any underlying conditions.

Babies have shorter and more active sleep cycles
It is perfectly normal for newborns to be squirmy and make a lot of noise in their sleep. Their nervous systems and digestive processes are not yet fully developed, and they are still adjusting to their new environment outside the womb. Their sleep cycles are shorter and more active, with a baby's sleep cycle lasting around 45 to 60 minutes. During the Rapid Eye Movement (REM) stage, they may wriggle, twitch, or make noises. This is a normal part of their sleep pattern because their brain is highly active during this stage.
Newborns spend about 50% of their sleep time in the active sleep stage, which is characterised by eye movements, increased brain activity, and heightened muscle movement. They may also be squirming due to discomfort or hunger. For example, a newborn's digestive system is developing, and they may grunt as they adjust to digesting milk. They may also be dealing with congestion or acid reflux. A cool humidifier can help reduce congestion, and feeding adjustments can help with acid reflux.
It's important to note that if the grunting and squirming seem excessive or are accompanied by other symptoms, it's best to consult a doctor or pediatrician. They can help rule out any underlying conditions and offer specific advice based on your baby's needs. Creating a consistent and calming bedtime routine can also help soothe a squirmy baby. This includes a calm, quiet environment with little to no stimulation, and following your baby's sleep cues, such as rubbing their eyes or pulling their ear, which could signal that they're overtired.

Newborns are learning to defecate
Newborns tend to squirm and grunt a lot in their sleep, which can be startling for new parents. This is usually normal and is often due to their immature nervous systems and developing digestive systems. Newborns are learning to digest milk, which can cause them to grunt and squirm as their bodies adjust. They may also be dealing with acid reflux, congestion, or respiratory issues. Additionally, newborns have shorter and more active sleep cycles, resulting in more movement and noise.

Babies are adjusting to breathing outside the womb
Newborns often grunt and squirm when they sleep, which can be confusing for new parents. This behaviour is generally normal and is usually due to the fact that their nervous systems and digestive processes are not yet fully developed. Babies are still adjusting to their new environment outside the womb, and their bodies are learning how to function properly.
Firstly, a newborn's digestive system is underdeveloped and still adjusting to handling milk. During digestion, babies may grunt from gas and bowel movements. Their body is learning how to handle digestion, which can lead to discomfort and noise. A buildup of gas in the stomach or intestines can cause discomfort, and newborns may squirm or grunt to relieve this discomfort by passing gas. This is a common problem for newborns as they adjust to feeding.
Secondly, newborns are learning how to breathe and use their respiratory organs. Their breathing can become more irregular during sleep when they are more relaxed. This can cause them to grunt or squirm. Chest and nasal congestion can also cause irregular breathing, and a cool humidifier can help reduce congestion and make it easier for your baby to breathe.
Thirdly, newborns have shorter and more active sleep cycles than older children and adults, resulting in more movements and sounds. Their sleep is characterised by increased brain activity and heightened muscle movement, which might include twitches, squirms, or even brief vocalisations like crying or moaning. As they grow, their sleep cycles will gradually extend, and they will spend less time in active sleep.
Finally, newborns may also be grunting and squirming due to mild discomfort, such as a wet diaper, being too hot or cold, or needing a change in position. Paying attention to these cues can help meet your baby's needs. Creating a consistent bedtime routine that starts at the same time every night can also help your baby sleep better.

Establishing bedtime routines for newborns

Start Early
There is no right or wrong age to start a bedtime routine, but it is recommended to start as early as 4 to 6 weeks old. Newborns are often very sleepy, but as they start to stay awake for longer periods, a bedtime routine can help signal that it's time for sleep.
Keep it Simple and Flexible
A newborn bedtime routine does not need to be elaborate or rigid. Focus on a series of simple steps to help your baby understand it's time for sleep. Be flexible and follow your baby's lead, as their cues and body language will tell you whether they want to sleep, feed, or interact. It's okay to go with whatever feels right at the time and to try things in a similar order if that works for you and your baby.
Sample Bedtime Routine
A typical bedtime routine for a newborn can include the following steps:
- Give your baby a bath and play some soothing music.
- Swaddle your baby safely and snugly.
- Feed and burp your baby.
- Turn on white noise and rock your baby gently.
- Place your baby drowsy but awake in their crib.
Adjust for Older Babies
As your baby gets older, you can add more steps to the bedtime routine, such as brushing their teeth, reading books, and dressing them in a sleep sack. Incorporating nightly baths can also be a great way to help them relax and signal that it's time for sleep.
Address Discomfort
If your newborn is grunting and squirming excessively, it could be due to discomfort. Observe your baby's behavioral patterns and address their needs. For example, they may be hungry, have a wet diaper, or be too hot or cold. Gastroesophageal reflux is also common in infants, and feeding adjustments or holding them upright before bedtime may help.
Remember that each child is unique, and you may need to modify the bedtime routine as they age. Consult your pediatrician if you have any concerns or if the grunting and squirming seem excessive or are accompanied by other symptoms.
