Category Post Count In Navigation Menu

Hi! I want to add my categories to my menu – which I already know how to do through the Appearance –> Menu section. However, I want the post count number to be included also.

So for example, I would create a blank menu button then add may categories as dropdowns – I also want the post count to show as if it would in the side bar. I would like for it to look like this in my navigation menu…

Shoes
**Boots (12)
**Heels (9)
**Flats (17)

In a normal case, the menu would just show the categories in a drop down without the post count. Any ideas or suggestions?
