My 9 month old dtr woke yesterday morning with a fever of 100.6 and a slight cough. Throughout the day her fever went up and down between 99 and 101.6 without the use of medicine. She then had a struggle sleeping last night even though her fever had been gone for a few hrs. She finally went to sleep after giving her Hyland's Hepar Sulph. Calcium. She slept good and has not had a fever all day but does sound a little hoarse and sometimes has a very dry cough. Do I need to be concerned about croup or bronchitis? I do have a stethoscope and have listened. Her lungs sound clear to me, but I am not a nurse or MD and only use it to monitor my son's asthma.
