Hello, I hope some experienced sling users out there can help me!
Now that it's winter and my baby is getting heavy (around 20lbs/9kg), I've been using the ring sling a lot more than the Boba, since it's so quick and easy to use over any coat. But whenever I wear it for a while, my shoulder starts to feel compressed and sore, and it doesn't feel very healthy. It's hard to maintain a good posture too.
I thought this was because of the inflexible synthetic material of my sling (homemade, I realized after I bought it online). So I borrowed a friend's expensive organic cotton sling from Germany (brand Storchen Wiege, very well regarded in Europe), and I'm still having some of the same problem, to a lesser degree, but...
Now I'm wondering if it's something I'm doing, the way I'm built (kinda boney in the shoulders), or maybe the inherent design of slings and the way the weight is concentrated. Others with cotton slings have told me they don't have this problem (but nobody with the same skinny-tall type build). I spread the material near the ring over my whole shoulder, so it's more the general weight and pressure, and not that it's digging in, but it feels like a more flexible material might help. I also should mention I had no problem when baby was smaller/lighter, unless I used the sling all day.
Any ideas or tricks to control the weight distribution in the fabric? I love the convenience of the sling, so I really hope it's something I can fix!
