Isn't this great?
Here's the article.
Those would make cute baby hats too! LOL!!
Etsy is a great place to look -- there are lots of sellers who have knitted breasts or 'boob hats'.
A friend of mine on Etsy makes knitted breasts which I use for breastfeeding education -- hope it's ok to share that link: http://etsy.me/hC4Zke
Also, if you are looking for the hats these are great: http://www.boobiebeanie.com/
I love the picture with the original post, doesn't she look awesome?
