@Nancy,
We just returned from a trade show featuring literally dozens of brands, many of which will be reviewed on Polliwogged in the next several months - including not only a lot of startups and sling companies but some nice new options from Baby Bjorn! Any recommendations are welcome!
I wore my baby birth-35 lbs, and we live in a big city and never really used a stroller. For people who want bombproof but pretty carriers that are extraordinarily comfortable, check these out:
Scootababy hip carrier (knocks the pants off the hip carriers available at chain stores):
http://www.scootababy.com/buy.php
and the Beco Butterfly II, which has a removable infant insert and can be used for front or back carries, even for smaller babies: http://www.becobabycarrier.com/
Honestly, while the Bjorn used to be the only game in town, there are so many more comfortable--and just plain cuter--options out there now, that will work from birth to toddler. http://www.thebabywearer.com is the “zrecs” equivalent in the babywearing world. They have all kinds of detailed reviews, of both carriers and vendors, and all the information you can absorb. There are so many great buckle carriers now: Ergo, TenToes Clicks, AngelPacks, Beco....
