What should I do if my 9-month-old baby has nasal congestion?
Nasal congestion in a 9-month-old infant can be alleviated through methods such as removing nasal foreign bodies, applying warm compresses, and administering medications. Nasal congestion at this age may result from physiological factors or pathological conditions—such as bacterial or viral upper respiratory infections.

What to do for nasal congestion in a 9-month-old infant
Physiological causes: Hair follicles are present at the nasal vestibule. Under normal circumstances, these follicles secrete an appropriate amount of mucus to lubricate the nasal passages. In dry environments, this mucus may trap dust particles or bacteria, leading to increased nasal crust (nasal mucus/dried secretions), thereby causing nasal congestion. Gently removing the nasal crust with a cotton swab or other suitable instrument usually relieves the congestion.
Pathological causes:
Bacterial cold (bacterial upper respiratory infection): This is typically caused by secondary bacterial infection. Symptoms commonly include yellow nasal discharge, nasal congestion, coughing, sore throat, and fever. Treatment may include pediatric paracetamol–chlorpheniramine–pseudoephedrine granules or pediatric cold-relieving syrup, administered under a physician’s guidance.
Viral cold (viral upper respiratory infection): This is generally caused by viral infection. Typical symptoms include sneezing, clear nasal discharge, generalized fatigue, and nasal congestion. Antiviral oral solution or oseltamivir phosphate granules may be prescribed per medical advice.
