The lawyer for the parents who don't want blood from Covid-vaccinated donors being given to their baby says they want the best for their son.
The four-month-old needs a second heart surgery but it's been delayed by the parent's concerns over blood.
The case will go back to the High Court next Tuesday if the family and doctors can't agree before then.
Lawyer Sue Grey told Morning Report the parents have found their own donors.
Grey says there hasn't been enough testing done on blood from Covid-vaccinated people.
The parents are convinced any blood from vaccinated donors is unsafe.
But Immunisation Advisory Centre medical director and vaccinologist Nikki Turner says that is not true.
