Start wearing your baby from birth.Just like our baby carriers, we paid special attention to baby's hip positioning when designingour infant insert. The unique angled pillow base keeps your newborn's hips in a natural fetal position. Our double padded back panel ensures proper support for baby's curved spine and our thick head support ensures baby's head and neck are protected. Since newborns develop quite differently at the stage, we recommend using the infant insert until baby neck is strong enough to hold up his head (usually around 4 months).
