Okay, just another hijack, if that's ok I had never heard of the beco, but am now really interested. I had an ergo for a short while with my DD, but I have rounded shoulders and it didn't stay on very well. I don't know if I'll find a store in my area to try one on. Can anyone comment on the shoulder thing? The ergo always was slipping off of me, and I never felt that comfortable with how much of the baby hung out of it. (And I think she was at least one when I got it).
