My Moby and ring slings are both from etsy. They were used a lot with my son. He is almost three and I carry him in a BabyHawk Oh Snap sometimes (getting harder now that I'm getting bigger, but I can do it). I got a BabyHawk MeiTai for our little girl.
We started out with the Baby Bjorn. Let me tell you...the other carriers that I've used (above) were a million times better.
