Dr. Thomas Hale is the leading expert on medications and mother's milk. He publishes an updated version of his book every year. He has a website you can browse for info. This is all I could find on azathioprine:

You can search the whole site and see if you find more. I just have a wiggly kid on my lap right now so she's hindering my progress. :) Here is the main link to Dr. Hale's site:

I breastfed all 3 of my kids while taking all of my meds - remicade/humira, asacol, prednisone, and nexium. Sorry I don't have anything to tell you about azathioprine. My understanding is that it is a no-no, but Dr. Hale seems to say different. Maybe your GI or OB can get his book and read up on it.
To Gypsyfp: Get a 2nd opinion.
