The SC diet was going very well and we were seeing good improvement... until applesauce, and then me making the mistake of feeding Cyrus a few bites of smoked salmon on vacation. At least, that's my guess as to why things have gone wrong since last Thursday... it's the only "illegal food" that he's had (I didn't know it was illegal at the time I gave it to him). The applesauce we should have guessed would not work well based on previous experience with apple juice. I did make some pear sauce recently that *seems* to have agreed with him more, but then again - Cyrus hasn't been the same for a week.
We may start over this weekend and flush his system out once again. Theoretically, the harmful bacteria that this diet aims to eliminate should eventually die off by not eating anything illegal -- but the intro diet worked so well that it's almost worth starting from scratch again. We've really only added into his diet: legal hot dogs, mayonnaise, ripe bananas, applesauce, and pears. Tonight he got some baked zucchini as well. Going backwards doesn't seem like a stretch at this point. We'll see...
