I use a Rose and Rebellion sling for my 20m DD, and would love to continue using it for our new arrival this spring. I know that you can buy a newborn insert for the Ergo, but what does it actually do? Can I carry a newborn in a SSC, and if so, how do I go about doing it? I have some ideas about swaddling it, or putting it in sideways or something like that- am I on the right track? Or will the newborn insert for the Ergo fit into my R&R?
