What baby carrier worked for you, if you are a small mama? I had the BabyBjorn One, and although baby liked it, it was tough on the back. (It's pulled a disappearing act, so it's a good excuse to try something else!) It had the supporting hip strap, but my torso was just too short to make it effective. I've just recently found out I'm pregnant with #2, so I'd like something a little different for baby wearing this time around. Thanks for your suggestions!
