Newborn baby - best cArrier

Have you consider konny? I've heard that there's mummy with cranky baby and once they put baby in konny, baby sleeps for 5 hours straight. My LO currently is 7 weeks+ old, previously have colic issues at night, fussing and crying non stop and I nearly went berserk. So I tried to put her into my konny carrier, she stopped crying in 1 min! And sleep peacefully! Most importantly it's super easy to wear just like a t-shirt even though it works like a wrap.
