This is best for the baby’s physical development from newborn to around four months. 

 

The design encourages healthy maturation of the spine by supporting the pelvis, hip joint, and leg position rather than putting a baby in a compromising sitting position before the spine is ready. The ERGObaby Infant Insert  also supports the safety of the baby's head and neck in this critical stage of development.The ERGObaby Infant Insert  is a specially padded and shaped cushion that can be quickly and easily placed in the carrier and readjusted as needed. This design easily enables parents to ensure that their newborn is positioned correctly on the pillow, keeping pressure off the developing sacrum, and supports the development of the spine and hips. It snaps closed around the infant, holding the baby in a cozy, protected environment close to the heart, as well as in an ergonomically correct natural sitting position.
