Baby sling, Part II
I bought a sling from ebay. I bid on it a few days ago, but didn't win. Fortunately for me, the person who DID win backed out and I was offered to purchase it for my max bid price. All together, with shipping it is less than $20 - much better than that site I listed a few days ago.
It doesn't have the padded rails, but upon furthur research, apparently they are a pain because I can have a hard time getting the sling tight enough with them. Plus they make it hotter in warm weather -- this will not be an issue in December/January!!
