Nobody has replied to this yet?! Well, I'm new & maybe I'm reading it wrong. Let this be my first post...
I love, love, love slings! The one I love the best is the New Native Carrier & they have a website, just Google it. They're not adjustable, so you'll have to get the correct size. Medium fits just about everybody. Just check the measurements & make sure you fit their specs.
I've never owned a Hot Sling, but I think they'd be great too. My girlfriend has one & LOVES it. I have a few other slings that I'm not happy with. You just gotta try 'em out, to each his own, you know? Anyway, slings are the best for newborns so they can be close for warmth. They enjoy the rocking motion of your movements, it makes them feel secure & grow up to be a secure child. GL with your new baby!
