you will definitely need it if you plan to use it right away. It supports their little head in there and keeps them a little swaddled. Otherwise I don't think it would be safe. We used the insert for about 2+ months.
i don't have the infant insert. at first i wrapped him in a blanket and put him in (like you would with the insert). now he 'sits' in the ergo in the fetal position and does fine. i bought it at jillians drawers in ithaca and the woman there told me that that was how she did it. either way i think you're fine.

BTW we LOVE our ergo!!
