Used once but no packaging or instructions (although they can be found online). I chose this carrier because it seemed to be the most adaptive to accommodate an 8 inch height difference between me and my partner with most other carriers not suitable for my short height. The fit is very snug and my baby just hated it, she wasn’t a clingy baby, she never contact napped, even as a newborn she just wanted to sleep in a crib. I took her out in it once and she lasted less than thirty minutes. I tried several other carriers/slings and they just in general weren’t for her. If you are lucky enough to have a baby that likes close contact this would be perfect. It’s basically brand new but listed as very good because I threw away all the packaging.
