Rachel, I found the reference to the citric acid on the disorder details of this website. First time I had seen this. Our daughter A (4q21.22q21.23) has had terrible reflux since birth. Have tried Alimentum for a long time and then we switched to Good Start Supreme. Both have been okay, but she is still refluxing and thought this might be a good lead for us. A had bad reaction to Enfamil (AR, added rice) in the beginning and had bad diaper rash and diarhea. Same thing when she went on antibotics.
