You may be surprised I did not include carriers you see most often on the street, such as Babybjorn, Chicco and similar. Unfortunately these carriers, even if easily available, are not comfortable neither for the parent, nor for the baby. The stiff materials they are made of and usually a very narrow bottom panel mean the spine is not supported in its natural position. Please visit the online shop with wraps and slings or the Sling Library section to find better alternatives.
