Just wanted to give an upate in case anyone out there is trying to decide if they should BF while on Asacol. My son is a healthy, happy 8 month old now. He is huge(over 20 pounds) and a joy to be around. I have exclusively breastfed him and was on as much as 12 Asacol/day during my flare after giving birth(YUP, I flared just like last pregnancy). I'm now on 6 Asacol/day with no issues on his end. I had no choice but to BF as my son had the same protein intolerance to dairy/soy as my daughter did, so I can't say for sure if I would have BF with Asacol in my system if I HAD a choice, but I am pretty sure I would have. At least I would have tried and if he showed any signs of issues I would have stopped. My supply is starting to go down(I work fulltime) and so I have started supplementing a bit and he is getting eczema from it.
Other than that it looks like his protein sensitivity is starting to get better.
