A mum who claims she couldn't afford to feed her baby re-enacted killing him and telling him "it will be okay, you will never be hungry again."
Yulia Khabitova, 28, used a doll as she reconstructed her crime to Russian police.
Footage shows her visibly shaking as she reportedly confessed through tears to strangling him, digging a grave in a manure heap with a spade, and burying him in a blanket.
She claimed she "had no food left in her fridge" and the desperate child was "always hungry" .
Khabitova said she told the one-year-old boy, Timur: "It will be okay, you will never be hungry again.
"You will never cry again."
Policemen reportedly wept when they found the child’s makeshift burial in Ismailovo, Bashkortostan, Russia.
Khabitova initially claimed the child had gone missing before allegedly confessing to murder.
"I strangled him, wrapped him in a blanket and buried under the manure," she reportedly told police.
"I did not have enough money even to buy food for him."
The mum had recently got a job stacking food shelves and paid a nanny to look after her baby, but claimed she could not provide for the child.
The nanny said: "I felt sorry for the boy. He was hungry.
"I bought him baby puree food, vegetables and meat, I cooked hot meals for him."
"His mother said she did not have money for more food," the nanny added.
Khabitova, who also has a five-year-old daughter who was asleep at the time of the killing, has been detained for two months.
She faces between eight and 20 years in jail if convicted of "deliberate murder".
