Oh, poor baby...poor mama!! I would say that if your instinct tells you something is wrong, then definetly find another doctor, and push them until they do something besides say "Baby's fine!" If your baby has had a fever for more than 2 days, the doctors need to know that, and if they don't pay attention to that, I would yell until someone paid attention. Has the baby been vaccinated for anything recently?
