The infant insert is required to use an Essentials carrier from the first 7-15lbs.
The Insert is intended for use in the Essentials carrier. Essentials carriers can be used from 7-20kgs without an infant insert necessary, and with the infant insert, the Essentials can be used starting from newborn – (from 3.2 kgs.)
(There is no infant insert needed for the COMPLETE line of carriers as it is designed with an adjustable seat and can be used from Newborn to 20kgs without an insert.)
When the child no longer needs the added neck support of the full infant insert, the baby can move to the pillow portion only. This happens usually around 4 to 5 months but may vary based on the child. The child will continue to use the pillow until their legs completely fit the panel of the Essentials
