The baby carrier world exploded in the past 6 years . I would actually recommend looking at the following:
1. Newborn stage - stretchy wrap like a Moby Wrap and a ring sling (and the ring slings now are soooooo much prettier and nicer than what was around when it was just the NOJO/Over The Shoulder/Mayawrap original - their padded shoulder is awesome!)
2. Once baby is 6ish months old, I really prefer a SSC or mei tai b/c I do almost exclusive back carries (for naps, running errands, etc...). Ergo, Beco, Pikkolo, and Boba are popular SSC options. A wrap can work but I didn't find them nearly as comfortable or easy to use long-term (especially not out of the house though I did use some in the house). Babyhawk is a popular mei tai brand.
