Hi S.,
Regarding the ear infection, my kids are a little older, however, we have had great success "curing" ear infections with natural methods.
We use Garlic and Mullein oil (can get in at Whole Foods) in their ears at the first sign of an ear infection (this is why it is easier with older kids since they can tell me when their ear hurts). We just warm it up by holding the bottle in our hands for about 5 minutes, and then we put 2 drops in each ear, and some cotton to hold it in (if needed). As a side note, you have to know that their eardrum isn't perforated, which I read is about 5% of ear infections. In addition, we use homeopathic medicine, and echinachea. A book we use a lot is called Smart Medicine for a Healthier Child.
I hope this helps regarding ear infections. Regarding the doctor, I agree with everyone who said get a new doctor! I would also be hesitant to continue antibiotics without being more sure you are in good hands, and that the antibiotics are that important.
Good luck!
S.
