Got a call today that I need to have another ultrasound because one his kidneys wasn't seen good enough in the pictures AND then the nurse asked me if they had told me I was having a boy, to which I replied "yes" and thought, well I'd freaking hope so right??, anyway, after I told her that they had told me I was having a boy, she said "oh well they can double check that too" ... the heck??? It was more the tone in her voice that I didn't appreciate.
