I have an awesome baby sling that I use all the time that my fab sister in law made for me. But I'm always looking when other moms says, "This worked for me."
Here's a new one. 4 1/2-5 yds of stretchy fabric, cut in half the long way (so about 22" wide) and wrapped like this: http://www.mobywrap.com/t-instructions.aspx#WrapInstructions
Baby goes like this: http://www.mobywrap.com/t-instructions.aspx (check out the "hold" instructions).
Very cool because instead of slinging on one shoulder (which most baby slings do), this one wraps like a hiking backpack, with shoulder and hip supports.
If any of you have tried this, let me know how it works. I want to try it with my next baby (whenever that happens!).
Be sure to read the pdf for safety info and tips for exercising with your baby slung on (I've always wanted to do that!).
