The anti-vaccine mother who snatched her wheelchair-bound four-year-old from hospital has now had him taken from her by police and social services.

In a video posted to Facebook, police arrived at a Newcastle mother's residence on Friday to take her son.

The parents have been issued with a Court Protection Order and will front court on Tuesday.

The mother, 26, and her partner, 28, had taken their son from Brisbane's Lady Cilento Children's Hospital last month, which led to an amber alert being issued by police.

The four-year-old was found a day later in Newcastle, north of Sydney, and was later allowed to be taken home by his parents.

In the video, posted to Facebook on Friday night, the mother and police can be seen arguing, as the young boy cries in the background.

'I understand you're upset… but we can't leave here without the child,' a police officer can be heard saying in front of a group of people.

The woman recording the video explains 'the police are trying to take [my son]… they're going to put him on poisonous food and medicine again.'

The police appear to take the four-year-old away as his mother continues to argue inside.

In a statement NSW police said: 'At 4.30pm on Friday police attended a premises on Hunter Street in Newcastle in support of Family and Corrective Services regarding a child at risk.

After extensive negotiations a four-year-old child was taken to John Hunter hospital for medical assessment.'

The parents received a Child Protection Order via email dated May 17.

A grab of the email was uploaded to Facebook. It reads: 'We advise the Director of Child Protection Litigation has made an application for a child protection order in relation to [the boy].'

The mother posted on Facebook one day before her son's disappearance last month 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'.

The mother claimed on January 18 the Department of Child Safety threatened to take her son unless they took him to hospital that night to be fed.

'They still think that they have the right to feed my son this formula synthetic s***,' she said.

The mother said her son's health improved after he went off medication, started eating organic food and took medicinal marijuana.

'He's happy, he's stopped seizuring (sic), he's coming back and still it's not good enough,' she said.

The mother said she would take him to hospital but would insist he be given medicinal marijuana to keep him alive.

'I will be doing this and if they choose not to do it.... I'll walk out of that hospital,' she said.

'I don't care if child services have to get a court order to come get him, at least I know I saved my child and I'll keep doing it, I will not stop.'
