Rosdeep Adekoya, who was convicted of killing her son Mikaeel Kular, has an ensuite shower and a key to her own cell at Cornton Vale prison, the 'Daily Record' reports.
She was reportedly moved into her comfortable surroundings after complaining about threats from other prisoners.
She told guards that letters calling her a beast and a child-beater had been left outside her cell door.
Adekoya, 35, has also landed a job in the prison kitchen, which gets her out of her cell and allows her leftover food.

Adekoya beat Mikaeel to death over four days in January last year after he was sick following a family meal at a restaurant.
He had 40 injuries on his body when he was discovered in the woods.
His mother, who has four other children, hid his remains in a suitcase behind her sister's house in Kirkcaldy and told police he had vanished from the family home in Edinburgh.
Adekoya was in a special protection unit at Stirling jail until the start of this year.
She was then moved to mix with medium and low-risk inmates but she was reportedly targeted with threatening letters left at her cell.
She had avoided a murder trial and the possibility of a life sentence of up to 35 years after a court accepted her guilty plea to the lesser charge of culpable homicide.
Scotland's social services had extensive contact with Adekoya and her children before she killed Mikaeel.
It began after she left her kids alone in July 2012 and went drinking.
Mikaeel was put in foster care after the incident and only returned to Adekoya in August 2013.
