Ergobaby Organic Baby Carrier - Once baby was big enough, we switched to the ergo (we didn't buy the infant insert, so around 3 months). We've been loving it! It stays more solidly in place than the Moby, and is more secure when parents lean forward. I was actually able to comfortably play tag with a 5 year old boy while wearing my 4month old in the ergo. Since Mom & Dad are such different sizes, we each have our own so we don't have to constantly adjust strap settings.
