Coughs in babies can be due to mild infections or throat irritation and often settle with time. Cough syrups should not be given on their own, as their safety depends on the baby's age and condition. Keep the baby comfortable, well-fed and in a clean environment. Avoid exposure to cold air or dust that may worsen the cough. Consult your doctor to choose a safe and suitable option.

For a 4-month-old baby, most cough syrups are not safe because babies this young are very sensitive to medicines. Consult a pediatrician before using any medication, as they may suggest infant-safe cough syrups based on the child's condition.

For Alex Junior, use a children's cough syrup suitable for your child's age and weight. Choose a syrup for a dry cough or an allergy-related cough, and consult your doctor or pharmacist before switching to ensure it is safe.

For a 1.6-year-old child weighing 11?kg with a runny nose, Alex Junior can be given if a doctor prescribes it. The dose should follow the label instructions or a doctor's advice.
