I bought one of these today. I actually was going to go buy a moby wrap as recommended by Jackie but after I got to the store (Posh Mommy) today and checked them out, I liked the baby ktan better. It's very similar to the moby but it's sort half done already so it's easier to wrap around you and get the baby in.
I "wore" avery today while I was shopping because I'm not supposed to lift more than 20 lbs right now and I had so many people ask me about it. And - she loved it. She took some good naps today and it was much easier to deal with her.
