Most children average between five and ten colds a year, so it's smart to learn how to spot and soothe one! Often, an infant with a cold will get sick gradually, experiencing one new sickly symptom at a time. Cold symptoms include coughing, sneezing, and a runny nose with mucous ranging from thin and clear to thick and yellow. While a low-grade fever may accompany a cold, this symptom is usually short-lasting, and resolves on its own.
