It's a Gypsy Mama Bali Baby Stretch. I have seen people nurse in wraps, but I am still a wrap n00b so I have not been able to. It is pretty easy getting her in and out. There's enough stretch that I can pre-tie it and then stick her in and take her out.
To Trenell, MizKerri and geeky:
I pray none of you ever has to live in a communist state.

Geeky is my hero. She's the true badass. The badass who doesn't even need to be a badass. There aren't enough O's in cool to describe her.
