I have a baby bjorn synergy, a joey sling and a backpack style called deuter kangakid.

I like the baby bjorn synergy because it has a back support in it, but find it annoying to keep adjusting between me and DH.

So I got the joey sling for me, and I love it! More than I thought I would. I got it for for discreet breastfeeding and short trips - like the supermarket, or a mad dash in to the shops, but I have found myself using it more and more. I have even gone on walks with him in it as it is so much more comforting to him when he is grumpy or tired. And I have a bad back and I have not had any issues with it while using it. And of course yes, the funky design makes it all the easier to wear in public cos I didn't want a hippy look! And the reversible design means I can work out which colour is more suitable to me on the day And the other thing I like is that it is sized for me, and it is unadjustable. This means that I don't have to worry about anything slipping or giving way so as long as Jett is tucked in and the edges are up around him and he isn't going to topple out I can just get on with what I have to do.

The backpack we will start using once Jett can sit unassisted which he isn't quite at yet, but even then I think the joey sling will still be used by me as it is just so versatile!

HTH!
