I know it's a little early to be thinking of potty training Mac, BUT my sister just started potty training her two-and-a-half-year-old son yesterday. Her report: twice at the movies, once at Java Jungle, and twice at home.
It's fabulous that she got him to use the potty FIVE times on day one. But it's AWESOME that she took him to the movies and Java Jungle (bouncing bladders, anyone?) on DAY ONE of potty training! She started potty training on multiple toilets -- in public! Amazing!
So I told her that in a couple of years, I'm buying her a plane ticket to come out here and potty train Mac for us. Sounds to me like Aunt Coco could do it in a weekend!
