My baby mouth breathes: when should I be worried?

Babies are obligatory nose breathers. They should be breathing through their nose all the time. This is how they can have their mouth full with a nipple during breast or bottle feeding and still breathe. Mouth breathing isn’t as efficient as nose breathing — especially when it comes to oxygen absorption in the lungs. And breathing through the nose helps to filter out bacteria and irritants from entering the body. Babies should be breathing through their nose all the time, especially during sleep. And snoring with mouth breathing is NEVER normal.

Mouth breathing as an infant can indicate several things:

🤢Nasal congestion from an illness or allergies

😛Tongue tie

👀Large tonsils/adenoids

👃🏽Deviated nasal septum

🧠Learned habit

Prolonged mouth breathing can cause:

Atypical development of the mouth, nasal passages and face

• Poor quality sleep

ADHD

• Increased risk of asthma

• Swollen tonsils

• Dry cough

• Inflamed tongue

• Teeth issues, like cavities and bad alignment

• Foul-smelling breath

If you notice baby mouth breathing regularly (other than when sick), please make an appointment with a health care provider to help figure out the root cause.

• Stay away from your baby’s known allergens

• Gently push the chin upward to close baby’s mouth when sleeping

• Consult with a doctor as soon as you notice baby breathing through their mouth consistently

• Put a humidifier in their room to prevent their mouth from drying out

• Have tongue tie revised and work on suck training exercises, tongue posture, and body work for proper body posture to correct habits baby made from compensating for the tie
