Rice milk and soy

Went to the grocery store yesterday and got Lincoln Rice Milk.  I should know better than to buy ANYTHING without checking the label but when I say that Wild Harvest Rice Milk was on sale for 2.19 I grabbed 4.  After we get home and Nolan is putting away the groceries he says "Hey mom... Did you know there is soy in this?"  WHAT!???  I can't believe I didn't think to look.  It reminds me to check the labels even on things that I assume are free of certain ingredients EVERY SINGLE TIME.  Thank you Nolan for saving the day.  I would have been dealing with Lincoln and crying all night and not realizing what or why he was hurting.
