Bedside sleeper

A bedside sleeper, also referred to as a sidecar sleeper or bedside bassinet, is a bassinet or baby cot that attaches to the parents' bed, allowing newborns to sleep next to their parents safely. This is a form of safe co-sleeping, and has little risks associated with sudden infant death syndrome, unlike bedsharing. Bedside sleepers are a component of rooming-in, a practice followed in hospitals to keep the baby by the mother's bed, giving her time to establish a stronger bond with her baby.

A bedside sleeper is defined by the United States government as "a rigid frame assembly secured to an adult bed that is intended to provide a sleeping environment for infants." Usually, one wall of the bedside sleeper is lower than the others, which allows the parent to easily reach for the child at night. Most bedside sleepers are multi-mode, meaning that they can be converted into bassinets and/or play yards.
