If your 1-year-old daughter has been coughing persistently after having laryngitis a month ago, you should try using a nasal hygiene technique to see if it helps reduce the coughing. This technique involves using a syringe (without a needle) and saline or distilled water to help reduce the mucus flowing from the nose to the throat. Be sure to follow the instructions carefully and adjust the amount of water based on your child's age. Most parents see an improvement in symptoms within 48 hours of using this technique regularly.
