Baby Malakai has been alive for seven months and he's never left the hospital. The newborn cannot see, cannot hear and struggles to breath. Doctors say he may not ever be able to walk. Having been diagnosed with a rare medical condition known as Pallister Killian Syndrome (PKS), his mother had to give up her job in Perth in order to provide full-time care for her son. Without an income, Stacy Maitai has been forced to survive on welfare funding of $90 a week to support her baby and her seven-year-old daughter. And the 28-year-old is not eligible for further financial assistance from Centrelink as she is not an Australian citizen. Scroll down for video .

While Ms Maitai juggles her time between the hospital with Malakai and at home with her seven-year-old daughter Serenity, the financial strain of being without a job and dependent on $90 from welfare is taking its toll.

'Our power was cut off and I thought we were going to be thrown onto the street,' Ms Maitai said.

'You know, I came to Australia for a better life and I love it here. It's changed my life. I worked since moving here about four years ago and paid all my taxes. 'I was shocked when Centrelink told me I couldn't get any more assistance because I'm a Kiwi. 'With what I currently get every fortnight, it's hard to afford even just the basic things.' Not having grown up with a proper mother and father figure back in New Zealand, Ms Maitai is determined to give her children the life she never hard. 'I want to be a better parent and I want to be there for my kids,' she said. 'It's just a waiting game with Malakai and the doctors even asked me if I wanted to look after him even with his condition and I said yes. I chose to be there for him and he will make it through - I just know it.' Pallister Killian Syndrome, also known as PKS, is a rare chromosomal disorder.
