My nephew's foods couldn't touch each other either, but I was becoming anxious just hearing how many different things were on her plate at one time! I followed the one-bowl diet for a while - actually it's pretty much how I usually eat, one thing at a time, then if i'm still hungry, something else. She might be feeling overstimulated? I know my nephew had no control over anything in his life, so it came out in food issues. Are her symptoms just around food, or other things too?
