I just need some other mom's opinions. my son had a nasty ear infection that took 3 antibiotics to get rid of. He just finished his antibiotic a week ago. three days ago he started a fever ranging from 99.9-100.9. He was holding his ear last night, but not swatting it like he normally does and today his nose is a little runny and he has a phlegmy cough. I took his temp before bed and Motrin and it was 101.3. my question is how long before you take baby to the doctor? I feel like we are there at least once a month and I don't want to go for just a cold... but I don't know how long you let a low grade fever go. please help!
