A 17-month-old who passed away after she was hit by her family’s four-wheel-drive in South Australia is being remembered by her parents as a perfect and gorgeous girl.

Toddler Anna Seagren was hit at the farm on Victor Harbor Rd, Mount Jagged, about 55 kilometres south of Adelaide at 3:45 pm on Friday.

“The toddler was hit by the family 4WD,” police said in a statement on Saturday morning.

“Sadly, despite the efforts of paramedics at the scene, the 17-month-old girl could not be saved.”

Her mother was picking up her eldest daughter from the bus stop when the incident took place.

“We just didn’t see her come out,” Ms Seagren told  Seven News.

“I saw her as soon after I’d made the mistake so I knew she was gone.”

She urged other parents to “slow down, just don’t rush, take that extra minute” and “give them that last cuddle”.

Together with the little girl’s father, Danny Seagren, she said: “She’s going to be so missed.”

Anna was the youngest of three children, with a brother Jack, 3, and sister Grace, 5.

Ms Seagren told Seven News: “We’ve told the other kids that she’s an angel now.”

“She’s not going to come home … but we can still talk to her and we love her.

“And that we were lucky to be her parents for those 17 months.”

The mourning mother said her daughter was “really cheeky, really cuddly and affectionate”.

“She was just a perfect, happy, boisterous, gorgeous girl,” she told  The Advertiser.

She said Anna was “a lightning bolt” who loved to bounce on her “little jumpy unicorn” toy.

Major Crash investigators are currently looking into the tragedy.
