With DS I had the Ergo and loved it when he was an older baby but not the infant stage. I used the ring sling a lot when he was little but was never very comfortable with it and didn't feel very hands free. I never felt comfortable nursing in either of them and DS never agreed to it either. I'm terrified of nursing an infant while keeping up with my toddler so I know I need a great carrier. Is the Moby the way to go or is there something better? Any tips on nursing while wearing?
