I agree that since she's requested you as a partner, you should go to the professor and decline the "honor," citing her up front declaration of being a slacker and any past experience you might have had. That said, it's still possible that you'll end up with her on your team. Although I agree with others that school group work shouldn't be about dealing with slackers the way you would in the "real world," the reality is that it is. So, how would you deal with a slacker at your job, whom the boss refuses to fire or reassign? You first make sure that they aren't responsible for any critical item. Posters? Nope. Presentation? Nope. If you have to reduce her to "you can bring the cookies to the team meeting," then that's what you must do. It stinks, I know, but that is the reality. In doing that, by the way, I would let the professor know ahead of time how you plan to manage her and to document *everything*, including all of the meetings where she fails to bring cookies and brings her kid(s) instead.
