I know this is a little late...I just joined the forum and was looking through the discussions and thought maybe I could be of help. I was on Humira my entire pregnancy with no complications. I was, however, part of a national registry in which they called me every so often during my pregnancy and son's first year with lots of questions that made me nervous because it showed they weren't really sure what Humira did to the baby. I did not breastfeed though because I REALLY didn't feel like the research was there to say it was okay. My doctor told me yesterday (when I told him when I had my next kid I wanted to be off Humira so I could breastfeed) that small studies say it is fine. The whole "small study" still makes me nervous! Hope this helps some!
