Ever hear of those parents who go overboard with potty training prep by pulling up all the rugs and cling-wrapping the couch? Yeah, they're probably on their second attempt with an Aries kiddo. These daredevils will test your limits, urinate on every surface imaginable, and make you wonder why you had kids to begin with. There's a good chance that after three days of "naked time," you'll call it quits. Silver lining: their sense of determination, while certain to cause you all to butt heads, should assure you that they will learn to use the potty . . . eventually.
