why baby eyes are so watery in cold and cough

Question

Accepted Answer

When a 5-month-old baby has cold and cough, watery eyes can be a common symptom due to a few reasons:

1. Nasal Congestion: Blocked Nasal Passages: When a baby has a cold, their nasal passages often become blocked or congested. This can lead to a build-up of mucus that can affect the tear ducts, causing watery eyes. Increased Tear Production: The body's response to congestion can also trigger increased tear production, leading to watery eyes. 2. Sinus Pressure: The inflammation of the sinuses due to a cold can affect the tear ducts, making them work overtime, which leads to watery eyes. 3. Allergic Reactions: If the cold is accompanied by allergies, the eyes might water due to irritation or allergens in the environment. 4. Viral or Bacterial Infection: If the baby has a viral infection, such as the common cold or another respiratory infection, the body often produces extra mucus to fight off the virus. This excess mucus can flow into the tear ducts, resulting in watery eyes. 5. Environmental Irritants: Sometimes, dry air, dust, or smoke can irritate a baby’s eyes, especially when they have a cold or cough. The irritation can make the eyes water more. What You Can Do: Keep the Baby's Nose Clear: Use saline nasal drops or a bulb syringe to gently clear your baby’s nasal passages. Humidifier: Place a cool mist humidifier in the baby’s room to keep the air moist and prevent the nose from drying out. Elevate Baby's Head: Slightly elevating your baby’s head while sleeping can help reduce mucus build-up and decrease the chances of watery eyes. Warm Compress: A gentle warm compress over the eyes can sometimes help alleviate irritation and soothe the watery eyes. Ensure Proper Hydration: Keep your baby hydrated with enough breast milk or formula, which will help with mucus production and recovery. When to Consult a Doctor: If your baby develops yellow or green eye discharge, it could indicate an infection, such as conjunctivitis (pink eye), and you should consult your pediatrician. If the symptoms, including watery eyes, persist for more than a few days or worsen, it’s best to see a doctor.

In most cases, watery eyes during a cold and cough are normal and will resolve as the baby recovers.
