The mother of Breha Organa was a human female from Alderaan. As was customary among Alderaanians, she introduced her daughter to pacifist values. Her husband remained onworld during her entire pregnancy and for several months afterwards. She later told Breha that after she was born, she had a shift in her thinking where she thought about the future in a way she usually didn't.
At some point before the mission to Pijal in around 40 BBY, Breha accompanied her mother to help negotiate a treaty.
