A stuffy nose, difficulty breathing, and itching on the back of the neck in a 2-year-old may be due to a cold or allergy. You can use saline nasal drops, keep the child well hydrated, and try gentle steam inhalation. Since your child is having difficulty breathing, it is important to consult a paediatrician promptly to rule out infections or allergies and get proper treatment. Avoid giving adult medicines.

Acebrolin syrup should only be given to children under a doctor's guidance. The correct dose depends on the child's age, weight, health, and other medicines. To stay safe and avoid side effects, never give this medicine on your own. Always consult a paediatrician for the correct dose and duration.
