While not using a wrap, these links can be helpful with using a woven wrap as support. Instead of cutting your wrap (EEK!) just cross in the back!
I've read that using a wrap or ring sling as support allows you to be a bit more comfortable when you feel like everything is falling out. I can only imagine how helpful this would have been to me when I was pregnant with DS since he dropped so early!
If you try this out be sure and share pics and tips!
