I attempted the wrap cross-carry on my back with my 12mo this past weekend. I had trouble keeping the fabric under his bum when I was trying. Does anyone have any suggestions on how to do this? I was getting him onto my back by sitting on the couch - I had previously placed the fabric under him - I'm still a little scared to try to "swing" him to my back. Also, when I was successful (sort of) in getting the fabric under his bum I felt like I had to lean a bit forward in the carry - perhaps I had the fabric too loose? How do I prevent his head / neck from being cut into with the fabric? I would appreciate any suggestions!
