Dark chocolate can be given to kids, but in moderation and as part of a balanced diet. Dark chocolate contains less sugar and more cocoa solids compared to milk chocolate, making it a healthier option in moderation. However, it is still a source of caffeine and can have a bitter taste for some children. It is recommended to start with a lower percentage of cocoa solids and gradually increase it as children develop a taste for it. It's also important to keep in mind that chocolate should only be a small part of a child's diet, and that other healthy foods should make up the majority of their diet.
