Bumper pads are soft, cushioned materials placed around the inside of a crib to protect infants from bumping against the hard surfaces. They are designed to prevent babies from getting stuck between the crib slats and to reduce the risk of injury during sleep or playtime. These pads come in various styles, colors, and materials, often made from cotton or polyester. While they can enhance the crib's appearance, safety experts recommend using them cautiously, as they may pose suffocation or entrapment risks. Parents should consider alternatives like mesh crib liners for added safety.
