is occasional diarrhea normal?

My 8 y/o daughter has been on Remicade since 4/09 and has done pretty good.  She had diarrhea on 1/27 which i attributed to eating KFC.  No belly aches, just happened after we ate.  No poops for a few days.  Normal poop on 1/30 and then we ate chinese & she had another diarrhea right after that.  No belly aches.  No poops for a few days.  Normal poop on 2/2 and 2/3 then a very soft, almost diarrhea later in the evening on 2/3.  No belly aches.  she is due for her next invusion on 2/10.  Just not sure if this is normal as it has not happened before.  she was just @ the GI on 1/28 and all labs cambe back great.  Sed rate was a 10 and hemoglobin also in good range (i don't recall what is was).  She has an excellent energy level & no other complaints.  Just not sure if this is normal.  Do any of you others on Remicade still experience occasional diarrhea?
