Police investigate child's death
The boy's mother called an ambulance after he lapsed into unconsciousness at their Biggera Waters home.
He died before arriving at the Gold Coast Hospital around 10.30pm (AEST).
Police are treating the death as suspicious and are interviewing his 26-year-old mother, her 27-year-old partner and the boy's uncle who were home at the time of the incident.
Acting Superintendent Des Lacy says the boy's mother called the ambulance.
"The young boy presented to the mother not well, apparently went to bed and then got up again not well," Supt Lacy said.
"As a result he passed into unconsciousness ... there was no visible trauma that we can report on at this stage."
A post-mortem examination will be conducted later on Monday.
