I didn't use a sling when Delaney was born. Didn't even know they existed at the time. We had a snuggly (cheap Baby Bjorn thing) but Roger used it more than I did. I found it to be uncomfortable and Delaney never really took to it when I wore it. But this time around I'd love a great-fitting, comfortable, light-weight sling. There are so many out there now. How do you know which one's right for you? What sling(s) do you love?
