My son is in 1st grade, and the child that had it was in 5th grade, but she has a sister in kindergarten. Called his integrative medicine pediatrician to see if he should get an antibiotic for prevention. We have a baby in the house. So I am freaked. I know I have read on here that the antibiotic just lowers your resistance. Not sure what to do. Anyone been here, and what have you done?
