so I've got this sling that I've used three times. it's just basically a few yards of fabric that I tie on across my shoulder like a sash. I know a lot of you moms have this and love it, but I'm having troubles. it seems I've got it on as tight as possible, and yet Abryn still slides down to the point it's impossible to nurse and I can tell it sometimes makes her uncomfortable. when I do get her in the right position, she's just to the point of being too small so that when she nurses, the nipple gets pulled down and kinda hurts. I think it might be just that my boobs are too small. we'll start off to the park in a good position, but by the time I'm around to walking back home, I end up having to hold her the whole way if she wants to nurse. also, the thing slowly slides off my shoulder... it's just frustrating because I would love to be able to use this thing all the time completely comfortably.
