A: We usually recommend holding off chocolate until 24 months, Ceci, but I don't think she's going to let you take it away now! The reason we're cautious is that chocolate can cause allergic reactions in some children, most notably gas. But if she isn't showing any signs, she's obviously fine with it. As for the quantity of chocolate milk she can have each day, one serving would be enough. What we don't want to have her do is to prefer the chocolate over her regular meals, so it should be considered a treat. Don't forget that chocolate syrups and milk powders are usually full of sugar as well, and should be kept to a minimum.
