A portable crib, also known as a travel crib or play yard, is a lightweight and foldable sleeping space designed for infants and toddlers. These cribs are easy to set up and take down, making them ideal for families on the go. They often come with a carrying bag for convenient transport and storage. Many portable cribs feature mesh sides for ventilation and visibility, ensuring the baby stays comfortable and safe. Some models also include additional features like changing tables or storage pockets. They are a practical solution for travel, visiting friends, or even outdoor activities, providing a secure sleeping environment for little ones.
