If your child’s cough is caused by a cold, you can try the following methods to see if they can relieve your child’s discomfort. 1. increase the humidity in the room by using a humidifier. 2. use a sea salt nasal spray. 3. if there is a lot of snot, use a nasal aspirator for babies. 4. older children can also try taking honey orally, which may help improve the symptoms of the cough. The use of over-the-counter cough and cold medicines for children is not recommended, especially for children younger than six years old. This is because the price paid, such as the possible side effects of the medication, is going to exceed the benefits obtained from the medication and will not significantly reduce the patient’s symptoms. In young children, cough and cold medications are unlikely to be of much help and may instead cause serious problems.
