It doesn't matter what I do, I can't get Monty to settle into the right position in the Close Baby carrier. I get it all set up as in the instructions, but about five minutes after being in the sling, Monty seems to be hanging halfway down my chest, closer to my hips than to my neck. He's just over a month old and weighs about 9.5 pounds. Anybody got any suggestions, as it's really frustrating me - we bought this sling because it's meant to be soooo easy to use, and so far neither me nor my OH have got to grips with it at all.
