Do Babies Breathe Through Their Nose or Mouth?

by Laura Klein

We receive so many emails from Aussie parents asking for advice on the health of their newborn, who has picked up a cold (usually from an older sibling!)

Babies breathe through their nose, so a blocked nose from congestion can severely compromise the health and comfort of your baby.  

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 Aspirator)

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. It is their preference and biological reflex to breathe through their nose.  

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. 

As babies breathe through their nose, and often sleep with their mouth open, both areas can dry out quickly - particularly if airconditioning 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. 

Plain tap water can be safely diffused 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. Read more on diffusinng essential oils with babies here

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.
