I've worn Avi in a sling since she was about 2 weeks old. She loves the sling! Now, I ask her if she wants to be "slung" and she says, "yes!" Well, the other day she wanted to wear the sling herself and put her toy Hippo inside. I think she will make a very good mommy.
The practicality of the sling: it frees your hands so you can do lots of stuff, like take a drink of water.
P.S. thanks to my friend Paula who handmade this sling for me. It has been and continues to be my favorite. I take it on every trip we take (have it with us now in the Delta) and wear it all around Tierra Nueva.
