I have one that i alternate with a kkfp, i used it with joe, and i now use it with Noah... I LOVE it! You have to be careful to get the waistband tight enough, and when it is it actually takes most of the weight, so your neck/shoulder doesn't suffer... plus it's the only sling that my boyfriend 'gets'! (probably 'cause it's hemp, thus cool, and doesn't completely swaddle him!).
The great thing for me is that every month or so i have to move the waist band just a little bit tighter...
, but the downside of that is the bulge that it creates under
the waistband. hey ho!
They're incredibly quick and easy to put on (see above re boyfriend!) and when you're not wearing it you can roll it up and still wear it 'round your waist like a bum-bag (fanny pack).
I use the kkfp more 'round the house when Noah needs to be held, needs to sleep etc. and I use the hip-hammock when we go out...
good luck! let us know what you decide!
