For a 3-year-old with daily morning cold symptoms due to dust allergy, try reducing dust exposure by keeping the room clean, using wet mopping instead of sweeping, and washing bedding weekly in hot water. A paediatrician may recommend safe antihistamine drops or syrups if symptoms are frequent, but avoid giving any medicine without confirming the correct dose for your child?s age and weight.

For a sore throat with frequent sneezing, try warm salt-water gargles, steam inhalation, and plenty of warm fluids to soothe your throat. You can take a mild antihistamine like Cetirizine at night for sneezing and a throat lozenge for relief. Avoid cold foods, dust, and strong smells. If symptoms worsen, get a check-up to rule out infection.
