My kids is of age 2, had cough and cold for last 10 days, and then now getting fever like once in a day. Fever is not continues, but getting fever in the evening or night time for one or two hours. The cough and cold is subsided now after we consulted pediatrician. He is active and having all kind of food in the day time. Our worry is, why he is getting fever some time, even though its not continues.
