Antibiotics. Again.

The xylitol worked great for sinus infection, but unfortunately, my son got an ear infection from his last cold. So, back on antibiotics (second time this year). He usually gets mild antibiotic induced diarrhea, and I try to control that with probiotics. This time I'm adding zinc too. I've read a couple of articles showing the benefit of using zinc in small children in order to control diarrhea.
