I have the ergo baby and the wild bird ring sling. Love them both! The ergo baby is great for putting baby ony back for the long carries. The ring sling is great for easy in and out.
Ergobaby! (I am dying to try a hippie Joey with the next baby)
I loved the Hippie Joey for the immediate newborn phase (7lbs) and then the Ergobaby 360 carrier for once she was bigger (12lbs range)
