Soy milk bad for children?

[madamerogers]

I believe some soy has too much iodine....otherwise not sure why it could be bad. Has no calcium, unless added and can have alot of sugar....
I have had my ds on soy the last month -sanitarium essential- added calcium-he has had terrible poos, awful awful nappy rash, screaming and unwellness- if thats a word. But, i think it has made his symptoms worse. I have now put him back onto milk and am cutting wheat. I hope it helps him, maybe there are other things you could look at?
I myself am dairy and wheat intolerant, do you know if you suffer also?
