I've always used a Babybjorn babycarrier with my 2. But now we're about to ttc for dc3 and so I'm starting to think about baby things. One thing I've always wanted to try is a real sling, however due to a slightly weak back I'm a bit iffy about that. Then wraparound slings caught my eye. How easy on the back are they and how easy are they to use when BF, 'cos I know the Babybjorn wasn't really compatible (another reason why I'd love to give a wraparound sling a go).
