(and yes, this has been par for the course for the day and it's only about 9:45 a.m. Ellie is still in yucky poop phase of the flu... since Monday/Tuesday... and I think she is also getting an eye infection/bacterial conjunctivitis. Joy. But at least rubbing alcohol gets ink scribbles off a computer monitor!!!)
