I bought 3 slings before I came across the 100knots sling. Having used it, I must say that I now use it all the time and my other slings have all but retired! I carried my baby girl in there since she was born and my son is 2 years old and he still jumps into the sling cos he loves it! It is a really good design so even with my heavy son, it's quite comfortable and the most generous of all my slings. The lady doesn't make the slings herself, they are manufactured in Melbourne but she designed it I think. I know that they are the safest on the market cos they've been tested for everything and are approved by the INPAA which tests baby products. Whatever you decide, remember safety is paramount and looks come after cos it's a far drop to the ground for baby if the sling is cheap and not well made!
