Prescription History

I've been wanting to pull together a list of dates that Finn has been sick enough to require antibiotics.  From his prescription history, I have come up with the following from the last 2 winters:

11/3/2010--Bactrim
11/22/10--Augmentin  (If I remember correctly, he got the Bactrim at the end of a cold and right as he finished his 14 day course, he got sick again.)
12/30/2010--Bactrim
2/17/2011--Bactrim
4/26/2011--Bactrim (I filled this prescription but then he seemed to clear his cough before I ever gave it to him, so I held on to it.)
7/30/2011--Bactrim (I never called the clinic about this illness, but rather used the Bactrim that I had saved from April.)
9/28/2011--Bactrim
10/10/2011--Bactrim
11/7/2011--Augmentin
12/17/2011--Augmentin (I never gave him this prescription either.  I just threw it away.  He seemed to clear the cough on his own after starting his Pulmozyme, and I figured it wouldn't be long before another cold anyway.  I was right.)
1/10/2010--Bactrim

Considering each round of antibiotics last 14 days, the only month last year where he wasn't supposed to take an antibiotic at all was June.  Does it seem that he's sick more often than he should be to anyone else?  Typing it out, last winter doesn't look as excessive as it felt when we were living it.  But looking at the period from September to the present, it doesn't look good at all.  I just wish I could keep this kid healthy.  I'm really nervous about clinic on Monday, as he still has an occasional junky cough.  Here's to crossing my fingers and toes and just praying.
