How Nicole Millis Saved Her Son Sean’s Life?

During her interview with Med News in 2023, Nicole shared how Sean was born, his diagnosis with Hunter syndrome, and what she had to go through to get treatment. In addition, she admitted to being proud of her son and praised her hardworking and brave son.

She stated that her son was born premature and had to go through several tests to learn about the condition.

At that time, Sean was the youngest to be diagnosed with Hunter syndrome in Australia. As a result, his brain was affected in two-thirds since he was nine months old.

Even after several surgeries, no cure was found. In a quest to rescue her son, she found out there was a drug overseas for treatment. So, she contacted the company but it would take more than 18 months even if everything were to go as planned.

Lobbying the government was a more viable and quick approach. So, Nicole convinced herself and her husband to quit her job and lobby the government. After nine months of intense work, the drug was accessible to Sean, which eased his situation.

In the same interview, Sean Millis expressed his gratitude to his family, especially his mom, referring to her as his “inspiration.”

“Mum is inspirational. She’s tough and brave – like really brave. She fought for my lifesaving treatment. She is also really loving, and I have so much respect for what she does. She’s powerful, she works super hard, she’s a fighter.”
