Dickason admitted killing the girls by smothering them but denied charges of murder.
She had mounted a defence of insanity or infanticide on the basis she was so mentally unwell at the time, that she could not be held fully responsible for her actions.
After a high-profile five-week trial in 2023, a jury found Dickason guilty of three counts of murder.
She will be sentenced today by Justice Cameron Mander.
Dickason is facing life in prison, with Justice Mander to determine a minimum non-parole period, and where she will serve her time.
She remains in a secure unit at Hillmorton Hospital, and he may order her to stay there until her health improves enough for her to be transferred to a women’s prison.
If her health has improved adequately, she may be sent to prison today.
Justice Mander had ordered a number of detailed reports from psychiatric experts to help him reach an appropriate sentencing decision for Dickason.
Victim impact statements from members of the little girls’ family may be read in court.
