### Mouth Breathing in Infants: What You Need to Know Mouth breathing in infants can be a concern for many parents. Typically, newborns breathe through their noses. However, if there's a blockage in the nasal passage, they may resort to mouth breathing. Here’s what you need to know: #### Causes - **Nasal Blockage:** This can be due to a stuffy nose or more complex conditions. - **Jaw Structure:** Ideally, a child's jaw should be U-shaped and wide. Smaller jaws can lead to overcrowded teeth and obstructed nasal passages. - **Enlarged Tonsils:** Inflamed and swollen tonsils can partly block the airways, causing mouth breathing. #### Signs and Symptoms - **Sleeping Patterns:** Mouth breathing is often noticed when the baby is asleep. - **Habitual Breathing:** In some cases, it can become a regular habit even when the baby is awake. - **Jaw and Teeth Issues:** Slack-mouth overbites and V-shaped jaws can be indicators. #### Potential Health Complications - **Reduced Filtration:** Breathing through the mouth filters fewer toxins, which can inhibit circulation. - **Oxygen Transfer:** This affects the transfer of oxygen throughout the body, impacting overall wellbeing. - **Developmental Issues:** Long-term mouth breathing can lead to developmental issues in young and developing brains. #### Treatment Options - **Pediatric Dentist:** If you notice symptoms, make an appointment with a pediatric dentist. - **Referrals:** You may get a referral to another professional for proper diagnosis and treatment. Understanding these aspects can help you take timely action to ensure your baby's health and development.
