What is playpen?

A playpen (also known as a play yard, play enclosure, or play area) is a small, enclosed area designed for children to play in safely. It usually consists of a plastic or metal frame with mesh or fabric sides, and is typically used for infants and toddlers. Playpens can be used indoors or outdoors, and may come with a variety of accessories such as toys, activity panels, and changing tables. They are designed to provide a controlled environment where children can play and explore without the danger of getting into harm's way. Playpens are widely used by parents and caregivers to keep children safe and contained while they work or tend to other tasks.
