I never used one with my first 2 babies. I borrowed several types from friends and just never liked them. Then I had my twins and a friend introduced me to the Mobywrap. It was just what I needed to carry Greenbean around in when he was colicky and wanted to be held for 7 hours at a time.
If I were you, I'd do a little research to find out the best-loved ones and then see if you can borrow some to try when your baby is born. You might be surprised to find you love 'em or hate 'em.
