A heartbroken mum said she "will never reach closure" as a two-day inquest looking into her infant son's devastating death concluded on Thursday (January 6).
But the devastated mum said she is now angry and upset, and struggles to reach closure.
Speaking to Nottinghamshire Live just outside Nottingham's Council House after hearing all the evidence, Ms Ibbeson added: "It feels like a never-ending tragedy that happened to me.
"I do not know if I will ever find the conclusive answer - I am just very angry, upset and let down."
The second day into the inquest of 15-month-old Emmett Jago Rathband's death heard from more witnesses who were involved in the toddler's treatment.
Baby Emmett was seen by Dr Andrew Preyell and Mr Mat Daniel, of Nottingham University Hospitals Trust (NUH), in April last year, over concerns about his noisy breathing.
The toddler was taken on two consultations to Queen's Medical Centre, where he underwent a pre-operation called adenoidectomy and also tonsil shaving.
Prior to this, the baby had also undergone a sleep study at King's Mill Hospital, which determined Emmett was suffering from obstructive sleep apnea.
The findings prompted specialists at NUH to schedule a provisional date for a surgery to investigate the cause of Emmett's obstructive breathing. This was due to take place on July 13 at the latest, Mr Mat Daniel told the court.
However, this would have been months after Emmett was found dead in his cot at home in Alexandra Street, Kirkby-in-Ashfield, on May 2 last year.
The earliest possible date for him to undergo the surgery would have been a week after the baby died, the inquest heard.
Further investigations were due to take place at the Queen's Medical Centre in October this year, including potential discussions about Emmett needing a face mask or ventilation to help him breathe.
Dr Elizabeth Didcock, assistant coroner for Nottingham and Nottinghamshire, said that "while all the steps planned were correct - it might have been just too slow".
"I understand that work load might have affected this", she told the court.
"And I cannot say that this has caused Emmett's death - but we might have had a clearer picture now."
A pathological examination found the cause of death was a "combination of factors" linked to his diagnosis of Down syndrome, obstructive sleep apnea, chronic viral tracheitis and an anomalous right subclavian artery.
In response to the findings, Dr Preyell told the court: "Every-time a child dies it is a great tragedy.
"But in this particular case it just feels uncomfortable that we do not know the specific cause of his death."
In absence of another explanation, the inquest conclusion was that baby Emmett died of natural causes, in line with the pathological examination.
A spokesperson for Sherwood Forest Hospitals said: “This is a very sad case and we would like to offer our condolences to Emmett’s family for their loss.
"There is always important learning to be taken from these tragic events and we will ensure that we further review our care, processes and procedures following the conclusion of the hearing.”
A spokesperson for Nottingham University Hospitals Trust said: “We would like to offer our sincerest condolences to Emmett’s family for their loss. This is an incredibly sad case and we are sorry that our specialist teams were not able to do anything further to help Emmett prior to his tragic death.”
