Quick question for you moms. My 2 year old had the flu shot this morning. I was also told he had fuild build up in his inner ear. He cried all night with it last night. She said it was not infected yet but feared over the weekend it would get infected. So called in medicine but told me not to give it to him unless he started crying in pain or running a fever. Well tonight he has a fever of 102. Should I start the medicine or wait to see if its just the flu shot causing it.
