Query: Don't waste your money

I have used three infant carriers and the Bjorn just does not compare to the other carriers that are available. I tried it out with my daughter (she was 5 months old at the time) in the backyard and my shoulders were so sore after just 15 minutes that I came in and decided to return it. The straps pull at your neck and shoulders, rubbing in between the shoulder blades. And this was with a small, young baby! Spend just a little extra for the Ergo, a carrier that I am still using comfortably with my 14 month, 24 pound daughter.
