I don't know, maybe call the ABA & find out. We only knew there was something wrong with Matilda when she was 6 weeks old and at her check up I told the GP that she was screaming from 6-8 hours a day. I had no idea. At that time the GP did a full check up and found that Matilda had burns on the back of her throat from regurgitating stomach acid. Matilda had a healthy weight gain, fed every 2 hours & didn't sleep because everytime we laid her down, she was in pain.
