I'm trying to decide which sling for my new baby due in April. We had an ergo baby carrier for dd1 but this hurt my back so I'm hoping a sling won't be as painful. Any recommendations which of the slings will be best for a plus size mummy, I thought I had decided on the mama sling but then spotted the reviews on the Kanga wrap so now I'm stuck. I don't fancy the idea of using a sling library if they just rent them out, I want a shiny and clean new one!
