My 8-month-old baby's cold has turned into a cough (the mucus is there). What should I do?

To help your 8-month-old baby with a cough caused by a cold, it's important to encourage the expulsion of mucus by giving them plenty of fluids and increasing humidity in their room. This can help make the mucus more liquid and easier to expel. It may take a few days for the symptoms to improve, so continue with nasal hygiene techniques in the meantime.
