I wasn't a huge fan of the Moby, which is what I first used when Natalie was born. She wasn't a big fan either - she doesn't like to be confined.
But then I discovered Tulas. I learned about them from a friend, and then a baby blog I read, and then facebook. They're basically awesome. It's a SSC (soft structured carrier), so it has a buckle and forms to Natalie. It's like wearing her as a backpack (or front pack). I bought one with my birthday money, and it might be the best thing I've bought yet. It's so comfortable, and Natalie loves it - she can see what's going on, she's held, she can sleep there, and she can play with my necklace.

I don't foresee us stopping anytime soon - it's just easy. Maybe when bits is walking. The standard Tula has a weight limit of 45 lb (and there's a size above it!). But for now, we're loving babywearing.
