I answered this above. No. There is no parameter for the template tag bloginfo() called “child_theme_directory” or anything similar. To write in the child theme directory, use “stylesheet_directory”. That works. For a full list of parameters that this tag will accept, please read the manual. They’re all listed under the header “Parameters”:

p.s. Looking at the codex page above, I see there is a parameter call template_url. No idea of that will write in the parent or child dir. But it’s one you haven’t tried I think.
