I have an Ergo and a Beco. For back carry I am most comfortable putting the carrier on at the waist with the fabric off to the side at my hip. I put DD on my hip, pull the carrier up over her back and then put my left arm (I have it on my left hip) through the arm strap. Then I "bounce" the carrier to shift her and it to my back and then put my right arm through that strap. I then bounce her once or twice to make sure she's sitting deep in the pocket of the material and not down into the padded waist strap area. Once I feel she's in there correctly I clip the chest strap. I'm just not talented enough to flip her onto my back and pull the carrier up.
Mom to two amazing DDs ('07 & '09) and a fur baby.
