Thank you so much for the info. I just have a couple of quesions please. What is EPI? I have heard of the pinapple , however he has stress colitis and am always concerned with not wanting to cause a disrupt in regards to nutrition. You mentioned it is most commonly a result of behavior , he has been very clingy(following me around) nipping for attention( which we are addressing). I was off work sick for a week and home with him now went back to work yesterday and thought that was the reason. What are your thoughts?
