I have a moby, baby ktan, ergo, mai tei, woven wrap, maya wrap ring sling, maya pouch, hotsling, and a couple misc (yes, I have a problem ;-))
My 2 cents after 3 kiddos:
First couple months-
MOBY - When I have time to get baby wrapped up nice and tight in the moby, it is most comfy for me and baby. It is not easy and convenient for the run into the store, or outing like that. I tend to wear baby for long periods around the house when I need both hands.
