Mr Rees allegedly told doctors the first time they went to the emergency room on January 16, 2015, he had seen Isabella "holding a double-A battery".
On the first day of the inquest into Bella's death, her mother said she knew each time they went into the hospital they would be turned away.
According to The Herald Sun, she said: "I knew they weren't going to believe us.
"Because every time we went we had evidence - we were just disregarded."
The family released a statement via Facebook on November 13, "Yesterday the inquest into the loss of our beautiful Bella started in the Victorian corners court.
"It was a very emotional day and it’s going to be a big week for us all. Thank you so much for all your love & support.
"Our little girls story, is finally being heard."
The family also asked for donations due to the heavy demands the inquest has created.
The statement read, "This is not an easy ask...but we need help to raise some funds for the legal representation of Bella’s family at the Victorian Coroners.
"The Inquest into Bella’s death has been set for 12 November 2018.
"Bella’s family is currently looking at out of pocket legal fees of approx $50k to ensure Bella’s story is heard. If you can help with a small donation of even $5 or by sharing this fundraising link we would be most grateful."
The Rees family, since their daughter's tragic death, have raised awareness via the group Bella's Footprint.
