Recently there have been numerous recalls of children's costume jewelry for containing high levels of lead, small parts that could lead to choking or the presence of cadmium that could lead to toxic poisoning. The fact is that very cheap jewelry is going to be made with very cheap materials. Instead, let your kids play dress-up using unwanted jewelry you already have, or buy safe accessories made out of wood or vintage materials. Your kids will learn that jewelry is precious and not disposable. But most important, you'll protect their health.
