Form 5481: Yes, absolutely she includes the child(ren) in Box 6B, and lists them in Section 6B on the following page. It doesn't matter that she is not working to support them, it matters that she is responsible for providing for them and that they are dependent on her. And you include them, also, in Section B of the "Additional Family Information" form.
RobsLuv, could you please clarify which page you meant by 'Section 6B on the following page'?
thanks
