A four-year-old boy taken from a Brisbane hospital by his parents is being treated by doctors in NSW.
Queensland police conducted a frantic search for Chase Walker-Steven after he disappeared from Lady Cilento Children's Hospital on Thursday.
He was found safe with his father shortly after police located his mother on Friday afternoon in Newcastle in NSW, following an emergency appeal for information.
Chase was taken, along with his parents, to John Hunter Hospital so he could receive medical attention.
Queensland Detective Acting Inspector Grant Galston said parents Cini Walker, 26, and Marc Alexander Steven, 28, were co-operating with police and were unlikely to be charged.

"At this stage, no," he said on Friday afternoon.
"We were primarily concerned with the welfare of the child."
They are yet to determine why Chase's parents took him from the Brisbane hospital just after midday on Thursday.
But Ms Walker's social media posts confirmed she and her partner are anti-vaxxers who believed his condition was caused by immunisation and feared hospital food would kill him.
Ms Walker posted on Facebook one day before Chase's disappearance that they stopped vaccinating him at age two because it gave him seizures.
She also alleged the vaccination caused him to develop "spastic, quadriplegic cerebral palsy and undiagnosed, uncontrolled epilepsy".
She also wanted the hospital to to treat him with medicinal marijuana.
