Finally got my Baby K'tan delivered (got a deal from nobetterdeal.com! thanks to whoever introduced it to me!) and I'm so excited. I tried it out with Lil Miss Wagon and she wasn't very happy about it, but then I tried the Ergo right afterwards (which she has loved and fallen asleep immediately in several times before) and she wasn't having that either, so she was just not in the mood to be worn. But I love how soft and compact it is. The Ergo is so tough to take with you, but the Baby K'tan all fits in the carrying case (that the sash is made out of!) and you can just throw it into the diaper bag!
Oh, I got the Breeze version because we are quite the sweaty and warm-blooded family.
