Baby gates are safety devices designed to prevent young children from accessing certain areas of a home, such as stairs or rooms that may pose hazards. They are typically made of wood, metal, or plastic and can be mounted to walls or used as freestanding barriers. These gates come in various sizes and styles to fit different spaces and can be easily opened by adults while remaining secure against curious toddlers. Many baby gates are adjustable, allowing them to fit openings of different widths, making them a versatile tool for childproofing a home.
