Hello! Baby is 11 months old. Had fever for 2 days at 38-38.5. Doctors said it's rotavirus. No runny nose or cough. Only fever. We were given ibuprofen, aspirin and analgin 8/1. They said gums swollen. We have 8 teeth. Fever dropped to 35.7 after 2 days. And then rash appeared. Today we saw private pediatrician. She said this could be allergy to sweets. What do you think? You haven't had this.
