Ergobaby Infant InsertsThe ERGObaby Infant Insert carries the baby in the tummy-to-tummy position, hence the name 'heart-to-heart'. It promotes healthy maturation of the spine by supporting the pelvis, hip joint, and leg position rather than putting a baby in a compromising sitting or hanging position before the spine is ready. It has extra cushions at the back and bottom to support the natural curvature of a baby's developing spine. The ERGObaby Infant Insert also supports the safety of the baby's head and neck in this critical stage of development. Parents can carry their newborn close to their heart so they can remain attentive to their baby's needs and at the same time continue daily activities.
