Choking hazards are objects or substances that can block a person's airway, making it difficult or impossible to breathe. Common choking hazards include small toys, food items like grapes or nuts, and household items such as coins or buttons. Children are particularly at risk because they often put objects in their mouths. To prevent choking, it's important to supervise young children during play and mealtime. Parents and caregivers should be aware of the size and shape of items that can pose a risk. The American Academy of Pediatrics recommends cutting food into small, manageable pieces and keeping small objects out of reach.
