I heard about this, and just had to blog about it. I'm not nursing anymore, but I might have been tempted to buy one of these if I knew they existed. It's a blanket -type cover that secures around your neck and gives you great coverage while nursing. The fabric is breathable so your little one stays cool under there, and it comes in lots of cool patterns. And of course I love the name of this product!
