Can a baby catch a sinus infection?

My baby is 3 years old. I wonder if a baby can catch a sinus infection?

Yes, he can. If symptoms of a regular cold lasts for longer than 10 days, take him in to his doctor.
Can a baby catch a sinus infection? First of all, sinus infections are not contagious. Sinus infections occur because of a viral cold, or severe allergies that block the normal drainage flow of mucous from the sinus cavities. This blockade results in mucous buildup in the sinuses and over growth of bacteria. Small children have small sinus cavities and therefore can get these infections from a cold or very severe allergies. Whether or not to treat with antibiotics is very individualized and should be discussed with your physician

Thank you for your question. A child cannot technically catch the "sinus" infection, but can catch the bacteria that may cause the sinus infection, pretty much like catching a cold.
Hope this helps.
3-year-olds do not have well developed sinuses, so cannot generally get sinus infections. They do, however, get frequent upper respiratory infections that involve a runny, stuffy nose, and cough.
No, they can’t. Sinuses are underdeveloped till age 6-8 years old. 


Yes he or she can. Sinuses develop at different rates in children> At that age, the sinuses above the nose called Ethmoid sinuses are developed and can get infected. This may manifest as nasal congestion with yellowish nasal discharge that lasts more than 7-10 days. It is prudent to distinguish other causes of nasal congestion such as allergic rhinitis when both nostrils are involved or a foreign body in the nostril where the discharge is on one side only.
