A baby crib is a small bed designed specifically for infants and young children. It typically features high sides to prevent the baby from falling out and is made from sturdy materials like wood or metal. Cribs often come with adjustable mattress heights, allowing parents to lower the mattress as the child grows and becomes more mobile. Safety is a key consideration when choosing a crib. It should meet safety standards set by organizations like the Consumer Product Safety Commission (CPSC). Parents can also find cribs with additional features, such as convertible designs that transform into toddler beds, extending the crib's usability.
