Madeline was born in Brisbane, Australia. When she was born, doctors informed Rosanne Stuart, Madeline’s mother, that Madeline had Down Syndrome (Trisomy 21). After going into heart failure at 10 days old, Madeline had heart surgery weeks later. After she was born, doctors told Rosanne that her daughter would have a difficult lifestyle. Despite receiving negative feedback from the medical community, Rosanne was committed to helping Madeline live life to the fullest. Her modelling career began when she was 18 years old. Her love of modelling began in 2014, after attending a fashion parade with her mother Rosanne and said to her “mum me model”. Rosanne knew it would take a lot of work and dedication, and told Madeline if she wanted to commit to the journey, she would fully support her, which lead to Madeline dedicating herself to becoming a model and making her dreams come true.
