8 month old breathing through mouth

A blocked nose from congestion can severely compromise the health and comfort of your baby.  It is their natural preference and physiological reflex to breathe through their nose. 

If the nasal passage is blocked, it can actually be quite dangerous.

How To Clear A Blocked Nose

It makes sense to flush out and clear the nasal passages as quickly as possible, and as often is needed. 

We would recommend a 2 step process of 

1. Flushing each nostril with 2-3 squirts of saline spray. Saline spray has no medical or chemical dangers, so is safe to use daily from birth.

2. Clearing and removing all excess mucus in a few seconds via steady, battery powered suction (using the Snotty Boss Aspirator). Keep bub upright to aid in snot removal.

Breathing and sleeping are easier with a clear nose. 


Let's explore the idea of nose breathing a little more.... 

Dr Nina Shapiro advises that newborns and babies are "obligate nasal breathers" which means their natural preference and reflex is to breathe through their nose. 

If the nasal passage is blocked, it can be dangerous and uncomfortable. 

Whilst mouth breathing is not impossible, newborns have certain physical features that make it more difficult including a larger tongue, smaller mouth and elevated larynx. 

During feeding, the mouth is blocked by breast or bottle, so it's absolutely vital a baby can breathe through their nose. 

A motorised nasal aspirator, like Snotty Boss, can safely and quickly clear the nasal passages, in the comfort of home. Parents feel reassured when Snotty Boss is in the medicine cabinet, in case of midnight congestion.

As babies breathe through their nose, and often sleep with their mouth open, both areas can dry out quickly - particularly if airconditioners or heaters are being used in the room, as they severely reduce humidity. 

Dry mouth and nose can cause early waking. 

As well as keeping little noses clear with a nasal aspirator, hydrating the air with a cool mist vaporiser/diffuser also promotes good health and good sleep. 

Baby Humidifiers

The team at Rhythm First Aid Australia and Itty Bitty First Aid acknowledge that humidified air helps sick babies breathe easier. 

Plain tap water can be safely turned into water vapour in the ultrasonic vaporiser/humidifier from birth, and a few drops of organic essential oil, like lavender, lemon and chamomile can be added from around 3 months.

Around the age of 6 months, rapid physical growth moves the soft palate and epiglottis further apart, which allows your baby more freedom to breathe through the mouth. Although they can alternate effectively between nasal and mouth breathing, normal babies over the age of 6 months generally continue to show a preference for nasal breathing.

Even as adults, we know how difficult and uncomfortable it is to breathe and sleep with a blocked nose and congestion, so it makes sense to help our little ones have clear and hydrated noses, each and every day.

Can an 8 month old breathe through their mouth?

Like adults, babies can breathe through their mouths if they're stuffed up, but a congested baby is a miserable baby.

When should I be concerned about mouth breathing?

Breathing through the mouth all the time, including when you're sleeping, can lead to problems. In children, mouth breathing can cause crooked teeth, facial deformities, or poor growth. In adults, chronic mouth breathing can cause bad breath and gum disease. It can also worsen symptoms of other illnesses.

Do babies breathe through their mouth when congested?

If your baby has a stuffy nose they may breathe through their mouth, which can make it harder for them to feed. In rare cases, a stuffy nose can cause breathing problems. Usually, nasal congestion goes away on its own within a week.
