My kids love cocoa with warm milk. I just warm the milk in the microwave and then add 1 teaspoon of cocoa and mix well. But I have a friend who tells me that drinking too much cocoa is not healthy for kids. She said she has read it before but couldn't remember now why it is not healthy. My boy could drink 2-3 cups per day. So does anyone here know anything about health hazards from drinking too much cocoa?
