The visa problems prevented the children's Norwegian parents - a same-sex couple - from arriving at the hospital in time for the birth.
Knowing her diplomatic passport would grant her entry into the country, she boarded a plane to India, traveled immediately to the hospital, and spent the next several days caring for the infants until a relative could arrive.
