The SNP's Patricia Gibson said she is still haunted by the mistakes which led to her own "horrific experience of stillbirth".
She called for coroners in England and Scotland to be allowed to investigate stillbirths when merited to address errors in care.
Such an investment could help reduce the number of baby deaths in the future, the North Ayrshire and Arran MP argued.

Breaking down, she told MPs: "I know as many, many others do, the horror of losing a baby.
"My baby Kenneth would have been seven years old this Saturday, the very day when we reach the culmination of baby loss awareness week."
The MP and her husband had undergone five years of fertility treatment before the death of her only child.
"We are haunted by the potential wiped away so cruelly and so suddenly, so unexpectedly," she said.
"Haunted by the fact that it was completely avoidable.
"Haunted by the fact that all this grief and sense of waste was because Southern General Hospital in Glasgow, now called the Queen Elizabeth University Hospital, made a series of basic errors."

She said the hospital has refused to recognise that any mistakes were made, despite independent experts suggesting otherwise,
"This is an all too common story and demonstrates unwillingness to openly engage in a learning process when mistakes are made," she said.
