Common nasal symptoms of a cold in babies include a runny nose, nasal congestion, and sneezing. Other possible symptoms are tearing, mild coughing, or throat discomfort. If the infection involves the nasopharynx, there may be fever, sore throat, tonsillitis, pharyngeal disease, congestion and proliferation of lymphatic tissues, and sometimes slight swelling of the lymph nodes. The fever can last from two to three days to about a week. Infants and young children are prone to vomiting and diarrhea.
