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."[1] 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.[2]
