Besides the liquid Tylenol Or baby Motrin for any fever or aches, You know to keep him well hydrated with clear liquids besides his formies or breast milk. Since he is so young just give him water or baby juice that is diluted a lot. Don't give him any citrus as it far to strong and usually burns the baby's bum. Also you should have a humidifier where he sleeps to keep moisture in the air for his stuffy nose and chest. All you can do is keep him comfy and treat the symptoms. 4 months is pretty young to be sick, I would recommend taking him in the the pediatrician.
