Child Stock doesn't display on dropdown

[innocent92]

I am trying to show stock of child products and i'm not sure how to implement.
I am using stockable variants.

Parent is Yarn (in attachment Puffy)
Child is Puffy Colors.

I need to display how many balls of each color are available.  On the product page, I don't want Puffy to show up as low stock.  You can't buy the parent. 

I would really appreciate any insight.

I am using Joomla   2.5.11      VM 2.0.22a
