We're in the habit around here of playing hospital/doctor's office. I'm often ordered to be the doctor. Emily is almost always the patient and Hope is my eager assistant.
Yesterday, Miss Emily the Patient told Mummy the Doctor that she had a sick tummy because she had a baby in there. As I examined her I asked her if she knew if it was a boy or a girl:
E: It's a boy.
Me: Have you chosen a name for him?
E: Yup. Mustache. Because he has a mustache.
