A baby stroller, also known as a pram or pushchair, is a wheeled vehicle designed to carry infants or young children. It typically has a seat for the child, a handle for pushing, and one or more wheels that can be locked into position for stability while in use. Strollers come in various designs and sizes, with features such as reclining seats, adjustable canopies, and storage compartments to make it easier for parents to take their children out and about. They are commonly used by parents when they go on walks or trips, allowing them to easily transport their child while keeping both hands free.
