After the death of Abiyah, they kept his body inside their home for eight days, before embalming the body using frankincense and myrrh prior to a ritualistic burial in their garden.
Sentencing, Mr Justice Wall their son died “as a result of your wilful neglect of him.”
He said the three-year-old had a “catalogue of injury and disease” at the time of his death.
The couple heard that the judge believed they both realised how unwell their son was prior to his death.
“I am sure that each of you played a part in starving him and failing to get medical care for him when the need for it was obvious to you,” he said.
“When Abiyah died you did not call an ambulance or seek any medical assistance in the hope that his life could be saved.
“Instead you took his body into the back garden and there buried it.”
During the sentencing hearing, the court heard that Tai Yasharahyalah had been attacked twice in the week since he was imprisoned after being found guilty, including an assault in a holding cell while on his way to Thursday’s hearing.
