I too wanted the best sling/carrier and after exhaustive research, and having been given a baby bjorn, I bought the 'hug-a-bub' from nct catalogue.
I have not seen anyone else wearing it, and it is not mentioned 'best ofs' but I love it
My baby is 7 weeks old and I used it from 10 days old..she was 6lb 10 at birth and at 10 days she weighed 7lb. Unlike other slings or carriers, the head is supported so it is suitable for a newborn before they can hold their heads.
I cannot enthuse about this product enough, as it has given me incredible mobility..you can bend down easily to tie your shoe laces etc, you can even bend to touch your toes with baby inside(although not recommended!) Completely secure and hands free.
You get the video with your purchase to show you exactly how to tie it..several positions, pocket at front for tissues etc. One thing I really like about it is that little legs get covered by pocket so no worrying about those socks falling off/trousers riding up as they always seem to do!
Also it is not padded so not as hot as other slings...
I am so pleased I went the extra mile and bought it..only drawback..very expensive £50 for basically a very long piece of jersey cotton + video, but it is definitely the best baby thing bought so far.
Have a look
