This behavior is known as pica, which is common in young children and highly treatable. There is no specific medication to cure pica directly. Instead, the first step is to consult your pediatrician. They will likely perform blood tests to check for nutritional deficiencies, such as iron or zinc, which are common triggers. If a deficiency is found, the doctor may prescribe supplements like generic iron. If nutritional levels are normal, behavioral therapy and close supervision are the standard approaches to help redirect your child's behavior. Please keep dangerous objects out of reach while seeking professional medical guidance.
