"23-month-old baby with a cough and runny nose?"

If a 23-month-old baby is experiencing coughing and a runny nose, it is recommended to try nasal hygiene with saline solution to help clear the nasal passages. This can be done throughout the day and at least 30 minutes before bedtime, followed by suctioning any secretions. Encourage the child to drink plenty of fluids and monitor their general condition. If there is no improvement after 7 days, it may be necessary to consult a doctor.
