It is recommended to use a nasal hygiene technique to help reduce the amount of mucus flowing from the nose to the throat. This technique involves using a syringe (without a needle) and saline or distilled water. The amount of water to use per nostril may vary depending on the child's age. Initially, it is suggested to use this technique about 5 times a day for the first two days, then you can decrease it to 2 times a day. Many parents notice a significant improvement in symptoms within 48 hours. This technique can be especially helpful if your child does not have a history of allergies.
