The Ergobaby Infant Insert was designed for use with babies from newborn to age 4 - 6 months. It supports your baby’s head and neck, as well as spine and hips during those first crucial months of development. Once your baby can hold her/his head up for long periods of time and is comfortable with her/his hips in a splayed position, the use of the infant insert is no longer necessary. The Infant Insert supports the Natural Sitting Position, sometimes called the "Spread-Squat Position", with baby facing you in the carrier. The bottom pillow in the Infant Insert can be removed from the insert and placed inside the carrier, with your baby sitting on top of it. This allows babies from around 5-6 months old, who may no longer need head and neck support, to be at an optimal height inside the Ergobaby Carrier. 

* Note: These two developmental occurrences do not always happen at the same time, but do take place between 4 and 6 months. Since babies grow and develop at different rates, monitor your newborn’s development to decide when she/he is ready for the transition.
