My baby mouth breathes: when should I be worried?

- Julie Matheney

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

Does breastmilk cause cavities? Do I need to night wean?

- Julie Matheney

Were you told by your dentist to night wean your breastfed baby for concerns of it causing cavities? Extensive research has proven that there is no link between breastfeeding (nighttime or otherwise) and cavities. Breastfed babies can get cavities, though, so good dental hygiene is still needed.

.

What can cause cavities are nighttime bottles and not brushing teeth before bed once baby is eating solid foods. Bottles allow liquids to pool in baby’s mouth and sit on baby’s teeth for long periods of time. Breastmilk doesn’t pool in the same way because milk only flows when baby is actively sucking. When baby is latched appropriately to actually express breastmilk, it enters the baby’s mouth behind the teeth. If the baby is actively sucking then he is also swallowing, so breast milk doesn’t sit in baby’s mouth like it can with bottles. Sugars from table foods can sit on the teeth and bacteria in saliva uses these sugars to produce acid, which in turn causes tooth decay. Actively brushing baby’s teeth twice a day helps reduce these sugars from sitting on the teeth.

.

One Finnish study could not find any correlation between cavities and breastfeeding among children who were breastfed for up to 34 months (Alaluusua 1990). In 2013, Lavigne found, “that there was no conclusive evidence that prolonged breastfeeding increased the risk of early childhood cavities.” Valaitis et al stated, “In a systematic review of the research on early childhood caries, methodology, variables, definitions, and risk factors have not been consistently evaluated. There is not a constant or strong relationship between breastfeeding and the development of dental caries. There is no right time to stop breastfeeding, and mothers should be encouraged to breastfeed as long as they wish.” (Valaitis 2000).

So no need to night wean for cavities… but if you need the sleep I completely understand.
