Their eldest son, Stevie, who suffers from a variety of disabilities, including cerebral palsy, and his brother Ty, who is autistic, were constantly battling it out over the volume of the television.

But last month Starlight Children's Foundation granted Stevie a wish - a home-entertainment centre for his bedroom.

The wish included a widescreen television, video player, DVD player, Wii and a television unit.

Mary-anne says Stevie has had a "rough time" in life but always managed to smile.

"He's always happy, never sad. He just takes everything on, which is good for us. Even the doctors say he is a delight to work with."

Mary-Anne says the wish has also brought the family together.

"The Wii game gets us all in his room playing, so it's really giving us some quality time together.

"At the same time, it gives him some privacy if he wants to watch a DVD or something in his own room. He's rapt with it."

Mary-Anne says the Starlight Foundation has also provided Stevie with much-needed support during his various hospital visits.

"He loves Captain Starlight. If he can't get out of bed then they will come to him."

This Christmas, the Starlight Children's Foundation is hoping to raise more than $1.5 million to help more than 400 seriously ill children who will be admitted to hospital during the festive season.
