Hi. I've got both a Baby Bjorn and a Bubba Moe sling. My DD is 8 weeks old now and I've only just gotten her happily into the Baby Bjorn and find it great to use around the house when she's awake and content. The sling is great for when you're out and about because they can sleep snuggly, you can cover them up from the sunshine and wind, you can discreetly bf (I have bf while walking around the supermarket) and you can put them in different positions as they get bigger. My DH loves the sling too, it's got more street cred! If you can only get one I would opt for the sling but maybe by shopping around for instamce on ebay you could get one of each and have the best of both worlds
