What is the best way for a stay-at-home mom re-entering the full-time workforce to address the employment gap?

I have had a part-time job for the past three years and now there is a regular full-time position open that I want to apply for. I need to update my resume and want to include the extensive corporate experience I had prior to having my kids. I understand that I can address the gap in my cover letter but I am wondering what I should do on the actual resume. Should I just leave the gaping 10 year hole in my employment history? Should I list full-time stay-at-home-mom as a position? What are the practicalities of this situations when creating a resume?

P.S. I know I can google this, which I will, but here I am hoping for advice from the real people who are members of The Collective.
