Doctor can recheck: Babies ages 3-12 months 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 mucous is blocking the nose somewhat, people may try a few drops of saline, then gentle suctioning with a suction bulb. A doctor can recheck if more than 2 weeks' cold symptoms.
