Stuffy and runny noses are common in children. While nasal rinsing with saline solution helps thin secretions and clear airways, parents must ensure correct technique and appropriate frequency to avoid damaging a child's nasal lining, especially in infants.

Parents can rinse their child's nose before meals or bedtime. The frequency depends on the severity of the stuffiness, but should not exceed two to three times daily. Overuse can strip away the protective mucus layer, leading to a dry, irritated nasal lining and an increased risk of infection. Saline nasal rinsing is recommended for stuffy or runny noses caused by colds, respiratory infections, or after exposure to dust or pollution.

Parents should use a 0.9% sodium chloride solution purchased from pharmacies, rather than attempting to mix homemade saline. Dropper or mist spray forms are preferable; avoid high-pressure rinsing. Limit rinsing to two to three times daily, and discontinue when nasal symptoms improve. Always wash hands before and after rinsing, and ensure all tools are clean.

Parents should seek medical attention if their child exhibits symptoms such as yellow, green, or foul-smelling nasal discharge, a fever above 38.5 degrees Celsius, ear pain, or excessive crying at night. Other warning signs include rapid breathing, refusal to feed, or respiratory muscle retraction, such as chest or sternal indrawing.

While nasal rinsing is a home-based remedy, incorrect technique can lead to complications. These include otitis media, damage to the nasal lining causing bleeding, respiratory failure, or infection.
