We use organic soy milk from Aldi and the kids enjoy it both as a drink and on their cereal. It's ok for cooking with, although makes sweet white sauce look a little grey so I tend to add blueberries or cocoa powder to it. Not too high in calcium which is an issue but we make sure he (my son who is allergic to cows milk protein) has access to calcium from other sources such as almonds, broccoli and other leafy greens. Coconut milk is also really good, great for curries and soups.
