Baby carrier tested grace consobaby with my daughter a month. Test conducted by dad and myself. I'm quite adept at carrying in a sling for little more about the physiological separation of legs. lack of position before the world does not bother me at all because I often find that children are improperly installed. however the back position is a major asset: the system to rotate the baby's belly position to the back door is simple (just hand to take already existing system for some backpacks). quality very strong and pleasant to the touch fabrics however, I had an older version of BabyBjorn baby carrier, the presence of the belt at the hips, distributes the weight well (test done with my son 2.5 years and weighing 12 kilo). the fastening systems make us safe and confident. They took time to adapt to understand how to put the baby gate but nothing complicated in the end. Dad and I had neither the same size or the same body size is the different settings in the back and the shoulders are not negligible. finally, baby carrier adopted by mom and dad. Dad even made the pub to his colleagues. great discovery
