I have an Ergo and am not very happy with it for back carries since I have a super long torso and my daughter only gets a view of my back, no matter how high I hike it up. I have tried a few high back carries with a wrap that I am borrowing, but can't seem to last longer than about 10 minutes thanks to back and shoulder soreness. Am I missing something? I have watched lots of videos on wrapping, but maybe I haven't found just the right style yet? My daughter is 19 months, very tall, and about 24 pounds if that makes a difference.
