We visited Mother Nature's this weekend and tried a few slings/carriers. We decided to get the Ergo Baby Carrier. It allows the baby's weight to rest on your hip instead of the back. And it can be worn in at least three different configurations - with the baby in front, on the back and resting on your hip (side). It can be buckled in a snap unlike the Baby Bjorn that requires a fitting process. It also has a front pocket/zipper to hold small items. Overall, seemed to be a much better fit for our needs.
We tried it on our yesterday's trip to Cape Meares (will post more pictures from the weekend soon).
Hope this carrier lasts us longer than the last one!
