(and started at 100lbs) She was 4lbs 13oz, but healthy. My second is 17 months and I took Remicade
which works very much like Humira
(which is what I take now) through my whole pregnancy. I had no flares or problems related to my Crohns, and I had ultrasounds every month to monitor her growth and development, and she was born as healthy as could be. That was a hard decision to stay on the medication, but the risk of a crohn's flare could have been devestating to me and the baby.
