calc. carb. for ear infections?

I have seen a practicing homeopath for my 2 year old boy who got his first ear infection middle November 2006 and has been treated with 4 rounds of antibiodics till today as the infection was coming back 4-7 days after we completed an antibiodic. Wanting to go away from the antibiodic treadmill we went to homeopath 4 days ago. At that time my son was at the sixth day of the last antibiodic. He said that at that time the eardrum was a bit red. He told me to stop the antibiodic and precribed calc carb, the first day to give it two times an hour apart and then the contents of a capsule every morning for 15 days. I read about this remedy and what worries me is that it says that the patient of this remedy is fat while my son is thin. Other characterists match though. What am I asking is whether this remedy is appropriate for a 2-year old with an ear infections which did not go away despite 4 different antibiodics and who at that time it had a bit of a red eardrum.
