child themes and get_stylesheet_directory

I am having an issue with loading some javascript in a child theme I am creating for one of my themes.

Essentially I do:

get_stylesheet_directory() . '/path/to/javascript.js'

which is what your suppose to do, But , as per the documentation, I am getting:

mysite.com/dev/home/path/to/wordpress/path/to/theme/path/to/js.js

which is causing it to not find the required file. because home is at the root of the site.

any ideas on what I can do to fix this?
