This problem may also have been started by all the Coke he drank over the weekend. Coke is very acidic. You are correct, your son's complaints are due to increased acidity with reflux. It is highly unlikely that he has a stomach ulcer.Give him an antacid such as Gaviscon Liquid 5ml twice to three times a day after meals for a few days and see if he stops complaining. If he continues then ask your paediatrician to see him.
