Is there anything that you all would recommend for a cold? He only coughs 1-4 times a day. His nose only runs once a day and it is usually clear to white. He is 5months and weighs 75lbs. This has been going on for 3 days now. He has great gutt sound, is still well intrested in food and water. He is just not a playful as usual. Please help me to help my little man out. Thank you.
