HE was nicknamed "Smily" and, along with his sister ­Elisha, was the apple of his ­parents' eye. Deepali and Nosh Mistry are struggling to come to terms with the loss of their little boy Ahan - run down and killed in the family's driveway. The 20-months-old suffered fatal head injuries after he walked behind a Toyota Kluger and was hit by the car as it was ­reversing out of a driveway in Hewitt Ave, Wahroonga, on Friday afternoon. He was rushed to the nearby Sydney Adventist Hospital before being transferred to the Children's Hospital at Westmead but died from his injuries. Ahan Mistry in his father's arms was nicknamed "Smiley" and enjoyed a family adventure to the Himalayas. Investigators sealed off parts of the road on Friday as they looked into the circumstances of the accident in the short but steep driveway. "At the end of the day, it's an accident for the Coroner to ­determine," Acting Inspector Andrew Ryabovitch said. Family members at the scene yesterday said the ­father Nosh had sent a text message about the accident. Neighbours have paid tribute to little Ahan Mistry saying they are devastated for the family. A distraught Mr Mistry ­politely declined to comment. "No thanks, not today," he said. Mr Mistry runs a photography business from the family home. He shot a video of a family holiday in India and the Himalayas in 2012, titled ­"Elisha - An Indian Adventure," in which Ahan was nicknamed "Smily." The video was narrated by his sister Elisha. The family, who moved into the single-storey brick Hewitt Ave home in 2008, were being supported by loved ones at the home. She was ­lovely, very friendly. We chatted for half and hour while the kids played," she said. It's a tragedy, the worst nightmare; they'll never get over it. Nadi Packo, who has lived a few doors down for 47 years, was shocked by the news. "Oh, my God, I spoke a ­couple times to the lady," Ms Packo said, describing the ­family as "very private." The tragedy follows a string of recent deaths of young children killed in and around driveways. Thomas McLaughlin, 4, was killed on the Central Coast by a 4WD earlier this month, and two three-year-olds were killed in November after being hit in driveways in Parkes and in Old Guildford, also by 4WDs.
