Nicole has already mentioned soy milk and whether it's good for children or not. If you decide that the Newsweek article speaks the truth, then read no further.
However, if you're an adult and drink soy milk, or if you and your children will continue to drink soy and rice milks, then perhaps making it at home from soybeans yourself is a good way to go, and also to ensure the quality of the product. This is the SoyaJoy soy milk maker, which can also make rice milk, almond milk and milks with other nuts/seeds. Because tofu is made from soy milk, you can also make tofu at home if you have the SoyaJoy. (Not that you couldn't make either soy milk or tofu without the machine).
The SoyaJoy sells for $137 retail, but until tomorrow, can be ordered directly from the manufacturer for $89.95 (though I suspect that the incentive "sale" price might be in effect for whatever holiday is next, as well).
