Women taking Remicade without 6mp?

I have a bit of a dilemma: whether to take Remicade in combination with 6mp or whether to take it alone.  My GI told me that most GIs in Canada recommend taking both together in the believe that 6mp reduces the chances that you'll develop anti-bodies to Remicade, rendering it ineffective.  However, he told me that one major hospital in Canada holds the opposite and that they prescribe Remicade on its own.

My dilemma presents itself because I'm thinking of trying to conceive and I want the fetus to be exposed to as few drugs as possible (although my GI feels comfortable with me taking both 6mp and Remicade while pregnant).  I'm also more comfortable with the thought of breastfeeding (something that is really important to me) if I'm only taking Remicade.

Does anyone have any experience with this?  Is anyone, especially any women out there, successfully taking Remicade without taking 6mp? 

Thanks for you help.

A year ago I had our third and final child but I personally would be a little nervous about being pregnant while on Remicade. I was on prednisone throughout my last preganancy and my photos from that time remind me how puffed up and borderline scary I looked but at least it kept me from having to use some of the hardcore drugs.
