Hi Katie, I hope it may help your friend. It was an awful experience for me,
and I can't imagine how awful it was for my daughter. I scoured the Internet
asking questions on a number of listservs. Based on one person's response, I
suggested a meat-based milk substitute but the doctors insisted that there
was a risk of vitamin A overdose (The fellow who had experienced this as an
infant said he was in good health, but he was only relaying what he was
told.) so we went with Pregestimil, then Alimentum. 

My daughter was also trying to breast feed, but Devon couldn't latch onto
the nipple.
  
Best Wishes, Ron
