A baby stroller is a wheeled device designed to transport infants and young children. It typically features a seat for the child, a canopy for sun protection, and a handle for pushing. Strollers come in various styles, including umbrella strollers, which are lightweight and foldable, and travel systems, which combine a stroller with a car seat for convenience. Most baby strollers are equipped with safety features such as harnesses and brakes. They can also have additional accessories like storage baskets, cup holders, and adjustable seats. Choosing the right stroller depends on factors like lifestyle, budget, and the child's age.
