He had just learned the color red and loved trucks and cars so much, he told them "bye" while driving away.
Instead, the toddler's friends and family will gather Saturday in Tuscaloosa for the boy's funeral.
His dad, Justin Ross Harris, won't be attending the funeral. He is accused of killing the toddler and is in jail, held with no bond.
The obituary does not mention the investigation into Cooper's June 18 death. It focuses on the child's life.
"He was loved and cherished and protected by both parents and all family members for his short 22 months of life," the obituary said.
"His 22 months of life were the most happy and fulfilling times of his mother's and father's lives, and we will miss him greatly. The family rejoices in the fact that we know that our Cooper is in the arms of Jesus fully restored, protected and in perfect peace."
The obituary was published Thursday and offered the first bit of information from Cooper's family.
Justin Ross Harris was arrested within hours of his son being pronounced dead in the parking lot of a Cobb County, Georgia shopping center.
According to police, Harris told law enforcement that he accidentally left his son in his car seat, in the vehicle, while he went to work at a Home Depot office.
He faces two felonies: murder and cruelty to children in the second degree.
Officers searched Harris' office prior to his arrest. According to the Fox5 in Atlanta, in the search history on that computer, law enforcement found that someone searched for information on how long it takes for an animal to die in a hot car.
We don't know the date and time of that internet search, but we do know it happened prior to Harris' arrest.
Harris will remain in the Cobb County jail without bond until at least July 15, when he's scheduled to again stand before a Superior Court judge.
Atlanta media report that Cooper's mother, Leanna Harris, was questioned by police after the boy's death.
She has not been identified as a suspect and has not spoken publically. She requested photos of Cooper from a laptop that was seized as evidence. Police denied that request.
Several Atlanta media outlets report that much of Cooper's funeral will be paid for by his father's employer, Home Depot's Homer Fund, which offers assistance of up to $10,000 to employees' families facing such a tragedy.
In lieu of flowers for Cooper's funeral, his family requests that donations be made to The Homer Fund, the obituary states.
Funeral services for Cooper will be held at 1 p.m. Saturday at University Church of Christ in Tuscaloosa, with David Eldridge officiating.
A private family burial will follow, with Tuscaloosa Memorial Chapel Funeral Home handling arrangements.
