A WOMAN has been charged after crashing a Toyota Hilux into a home in Merriwa in the early hours of yesterday morning, killing a sleeping eight-month-old baby inside.

It will be alleged that at 2:30am, the 35-year-old woman's vehicle mounted the median strip, ploughed through a wooden fence and into the wall of Nate Dunbar's bedroom in the Tug Cove home his family lives in.

Emergency services tried desperately to save the baby boy, but tragically he died from his injuries.

The Quinns Rock woman has been charged with dangerous driving occasioning death. She is due to appear in Joondalup Magistrates Court on February 11.

Grandfather Stephen Clarke said Nate was an amazing little boy.

"I just don't have the words to express how I feel at the moment ... so sad,'' he said.

Mr Clarke also thanked police and ambulance officers for their help, and the media for their sympathy.

Nate's grieving family made a brief statement earlier today asking for privacy.

Meanwhile, a candlelight fundraiser has been organised for Thursday, January 31, at Kingsbridge Park, Butler.

The organisers are asking for coin donations to help Nate's family and a Facebook page has been set up for the event.

Police will investigate if alcohol was a factor in the crash.

The driver was travelling along Hester Avenue and mounted a kerb before going through a wooden fence and colliding with the rear brick wall of a house in Tug Cove, Merriwa.

The woman - the only occupant of the Toyota Hilux - was taken to Joondalup Health Campus for treatment but reportedly walked from the scene to an ambulance. She is in a stable condition.

The State Emergency Service attended the scene to help stabilise the house and the woman's car was removed and towed away.

Two women from United Care visited the family home with flowers and a teddy bear, as a steady stream of family and friends came to the house to comfort the grief-stricken family.

Police say they plan on doing skid tests later today.

Major Crash investigators are urgently seeking information and want anyone who heard or saw the incident or have information to contact CrimeStoppers on 1800 333 000.

Merriwa is a northern suburb, about 32km north of Perth, in the Shire of Wanneroo.
