Runny Nose in Children

Common Causes

• Viral infections — Colds or RSV are common in kids due to close contact at school or daycare, irritating nasal passages.
• Allergies — Pollen or dust might cause itchy, watery noses, similar to adults but often harder to pinpoint.
• Foreign objects — Kids may insert toys or food into one nostril, prompting foul-smelling mucus from that side.
• Adenoid issues — Enlarged adenoids (tissue behind the nose) could block drainage and increase mucus.
