he is probably allergic to red dye

go to the doctor and have him tested. thats the only way to find out

With the "drinks" your feeding your son, theres alway's partially hydrogenated corn syrup, citric and folic acid makes gives the drinks its "tang", and there countless other specialty dyes used by the same companies

he could be allergic to lose two gums or an ingredient in the dye. theres more than one recipe to make food dye. remember how a few years ago they brought back blue m&ms because they made a new recipe for it because the other one they were using was proven to have something in it that upset ppl? same concept with the red dye. Just because one thing that has red dye doesn't upset him doesn't mean hes not allergic to them all because different co use different recipes for their dyes. But get him tested like they say u never know untill u try. U wont really know what the culprit is untill u get him tested.

You think Hawaiian Punch is some essential drink for kids? You ever hear of milk?

what a well informed panel we have here. they're all quite accurate. ween 'em all off of any corn syrup product, all sugars and anything with that red dye in it. there is a childrens sport drink/hydration formula that is so good, i drink it too. it's called innergize. comes in lemon, orange and punch. the punch has extra calcium for kids. go to the site below and let me know what you think.

it might be a good idea not to give anything but water & juice to your child. The artificial colors have been shown to have horrible side effects on kids.

red dye. a common allergy

Take him for an allergy test.
