SINGAPORE - Ms Jaiyesthri Ramasamy wanted to leave her two sons with her aunt before heading to Choa Chu Kang Christian cemetery for a relative's burial.
But 31/2-year-old Kryshan Nirmal Kumar refused to leave his mother's side.
"My little one was too attached to me," said the griefstricken 30-year-old, who saw her boy killed at the cemetery last Sunday, when the private bus which took them there ran over him.
"The tyre hit him, and ran right over him. I heard his skull crack, and saw the blood splatter," recalled the pre-school teacher, breaking down in tears.
"I can still see the whole accident, him being so helpless. It's the only thing that flashes in my mind. I don't blame anyone. I just want my son to come back to me."
Kryshan was buried at the Choa Chu Kang Hindu cemetery on Monday evening in front of around hundred friends and family members.
When The Straits Times visited Ms Jaiyesthri at her father's four-room flat in Woodlands where she lives on Tuesday night, there was a shrine for him, with strawberries and cherry tomatoes arranged in front.
"Those were his favourites," said his mother, with her other son, five-year-old Arshavin, sleeping beside her on the couch.
It was his younger brother who was particularly close to their mother, who described how Kryshan would wait up for her each night to go to sleep.
She finds it hard to come to terms with how she could only look on when her young one was being crushed.
"I keep losing sleep over that," she said, insisting that she was holding on to both of her sons when the tragedy happened.
"I'm a very careful person. I'm always very cautious on roads. My two sons have always been safe crossing bigger roads with me. I would not have let go of my sons' hands."
