I have a 11 weeks old child. has a cough and sneezing. she doesnt have fever and no mucus. what can i use to ease the snizzing and coughing ?

Some thoughts...: Infants can easily catch colds from other people. If there is just a runny nose, without much fussiness, without any high fever, without other worrisome symptoms, then parents can leave the nose alone. If mucus is blocking the nose somewhat, can try a few drops of saline, followed by gentle suctioning with a suction bulb. A doctor can examine younger or more symptomatic babies, such as wheezers.
