She is having problems with her 9year old son. Until about a year and a half ago, he was a quiet, shy, polite boy. Now he goes through phases of ADHD
-like behavior and she has linked it to milk intake. He is "normal" until about an hour after drinking milk or having milk in his cereal. She has eliminated milk for a week or more at a time and had NO PROBLEMS with him...but as soon as he has milk again he is hyper, rude, inattentive, etc. This subsides after a few hours.
