The mother of baby Anastasia Hand has faced court over the "sad and tragic" death of her daughter.
Cassie Doohan, 18, was charged overnight after officers received the summary of a post-mortem examination of her infant daughter, Anastasia Rose Hand, according to ABC.
Baby Anastasia was just 4 months old when she died, and doctors who treated her said she suffered a "catastrophic brain injury", which couldn't be an accident.
Anastasia's life support machine was turned off on May 28, two days after her father David Hand, 21, found her unresponsive at home in Capel, Western Australia.
The baby's father told the court he gave her a bottle of milk and his daughter appeared happy, making "cooing" noises. But when he came back 15 minutes later she was unresponsive.
Anastasia's injuries included swelling and bleeding on the brain as well as "abnormalities to lower limb bones which were suggestive of abuse".
After their daughter was rushed to hospital, the parents were questioned but later released.
Anastasia's family asked that their baby girl be christened in hospital before her life support was turned off.
Ana's grandfather said his son was "not doing well at all, he's totally devastated really, he's lost his whole family now".
He has set up a GoFundMe page to help his unemployed son pay for their child's funeral.
"David and Cassie tragically lost their beloved baby girl," he wrote on the page.
"David is unemployed and has no way to pay for his precious child's funeral.
"I am sending out this appeal to help them, so that they can grieve for their loss without the added stress of this financial burden."
Cassie Doohan has been charged with aggravated grievous bodily harm.
Her request for bail was denied.
The court heard the charge against her could be upgraded once police get the results of tests on little Anastasia's brain, which won't be until September.
