This is not normal. Have they seen another doctor?
The pediatrician had my older son on antibiotics over and over and over for a full year, so I took the kid to my general practitioner, who said his little system was off balance in part from all that pink stuff. We took him off it, gave him baby Tylenol instead, and the doctor made arrangements for me to be able to bring him in any morning or afternoon without an appointment if needed. He got better and didn't get another ear or throat infection for a long, long time.
