Results when starting diet with older kids

[Guest guest]

Has anyone started the diet with an older child (mine is 8) and

noticed appreciable results, or is this something you really had to

catch earlier than this. My son has many non-specific type things

going on (possible aspergers/adhd/?). He was quite withdrawn when

younger and had severe speech problems but those are pretty

resolved. He just acts like he is kinda " crazy " sometimes-saying

very strange things, etc.., Interested in if this could be related

to the " narcotic-like " effects of gluten or casein. We tried dairy

free for about 3 months a short while ago and saw no results. Any

advice/experience appreciated. Thanks! -Meggie
