I've got a Beco which we love - I like the material between me and baby which Lilfatty mentioned. It means I can put the carrier on, put baby in, undo the straps and pass her to DH like a backpack when I want him to take her
BUT, it took awhile of fiddling to get the straps right so it is comfy to wear IYGWIM. And after trying an Ergo, I found that a bit more comfy, although I don't like the low back.
In all honesty, I will be going for a Manduca next time - that is suuuuuuper comfy!
But yes, Beco prints are sooooo pretty
