Krishan Saujani died at Leicester Royal Infirmary in the city of Leicester in November 2015 after being taken to the hospital for vomiting and diarrhoea.
His mother, 33-year-old Bhavini, told an inquest at Leicester Coroners Court that she felt the hospital staff ignored her and husband Shalin's growing concerns over their son's condition, who suffered from Down's Syndrome.
"I just felt that we weren't being listened to when we were raising concerns about his low oxygen saturation levels. We were being told that the machines weren't picking it up, it was explained away as a machine error," she told the hearing.
"Someone needs to take accountability and responsibility for what's happened," she said.

Krishan's father also gave evidence to the inquest, which concluded today.
"Krishan was my best mate, I called him my little buddy. We planned to do so much together," the 35-year-old said.
Their son had a weakened immune system and was more vulnerable to infections due to his condition.
Earlier in the week, the inquest was told the boy should have been moved to intensive care earlier and the head of paediatric services at the hospital in Leicester, doctor Samantha Jones, apologised for his death.

Manish Arora and Nehal Thanawala also gave their evidence to the inquest hearing.
While Arora told the court that he did not think the boy was critically ill, Thanawala said she had been "very concerned" about him.
Expert witness Simon Nadel from St. Marys Hospital in London said the original diagnosis of vomiting caused by viral gastroenteritis "clearly in retrospect was not correct".
At the end of the inquest, Coroner Lydia Brown ruled that Krishan's death was caused by "natural causes". However, the family may consider legal action over medical negligence.
