What is Newborn without insert?

Newborn without insert means the carrier is designed to hold a newborn as it is, without an added liner, insert or head support cushion. It saves money and space, and it removes guesswork in the first weeks. BabyBjorn states newborn without insert as yes, and Baby Tula does the same for its cotton carrier. If a page does not say so, assume you will need to buy the insert separately.
