Balancing Fame and Family Life
Despite her mother’s fame, Oona’s parents have been very careful to keep her childhood as normal as possible. They wanted her and her sister to enjoy simple things—family dinners, school events, and time with friends—without the constant attention that comes with Hollywood. Sarah has often mentioned in interviews that family always comes first, no
matter how busy her career becomes. She made sure to plan her filming schedules around her children’s needs, and even when working long hours, she always found time to be present at home. This approach helped Oona grow up in an environment where love, respect, and balance were more important than fame or glamour. It also gave her the confidence to enjoy her mother’s success while still feeling secure in her own identity.

She has visited her mother on set and watched her work in a professional environment filled with creativity, teamwork, and long hours. However, unlike many children of actors, she has not shown any public interest in becoming an actress herself. Instead, she seems content with keeping her private life away from public attention.
Her parents have always made it clear that she is free to choose her own path, whether it leads toward the arts, academics, or another career entirely. This open approach helps Oona feel supported without any pressure to follow in her mother’s footsteps.

Her parents encourage open communication, kindness, and curiosity—qualities that help children grow into well-rounded and confident individuals.
