Lynda - always look to diet. How much sugar from packaged, processed foods does he take in along with preservatives, food coloring, chemicals, taste enhancers that are stimulatory. Hopefully he isn't allowed candy or soda and processed, highly sweetened cereals can be very unhealthy. Sometimes even natural sugars as in an apple prove to be too stimulating for some children. Do a google on the Feingold diet for hyperactive children. One of my little patients was helped tremendously by Feingold. He was so stimulated by many foods...even natural foods... that he just couldn't sit still. He would say to his mother... "I just can't help it but I can't stop." He was unable to eat an apple.... it may have been pesticide residues. Back then, we weren't as 'aware' as we are now. Organic is the way to go with fresh produce.
