I went onto Baby Bjorn?s website and found several articles relating to the safety and reliability of the product, and the fact that it is the only carrier that The AUSTRALIAN college of Midwives endorse, kinda sells the point to me.
Well they're not going to have articles that denigrate their product are they?!

Have you tried anything other than a BB? I am not a carrier afficionado but I have tried commercial carriers and then moved onto ergo, then scootababy, then beetlebums (1/2 buckle with mei tai straps) and finally a sling from bear hug baby... I actually bought the sling before the beetlebums but only just found the confidence recently to try something that wasn't structured! I found it awesome and so easy to carry around. Anyway the point is that in terms of comfort for myself and bubs I threw the commercial carriers in the bin. I can walk around all day in the ones I have now with no effect.
