Oh, another point is: with most slings and wraps, but definitely with the Ergo and HAB, you can wear your baby up to a much higher weight. The BB synergy for example only goes up to 12kg. The Ergo however goes up to 40lb (18kg). So handy for travelling with a toddler. And I know what I'm talking about having made a 30 hour trip to Germany twice (just DD and me, no other support person. First time she was 8 months, second time she was 16 months).
