More families should come forward, according to the senior midwife leading a review into shortcomings in Nottingham's maternity services.
More than 900 families had spoken to them, according to Donna Ockenden, who oversaw a previous review of the Shrewsbury and Telford NHS Trust.
400 current and former employees of the Nottingham University Hospitals NHS Trust have also been in touch, she continued.
She said, "I am aware of how challenging taking the first step can be.
Sarah Andrews is one mother who is in favor of the appeal. In 2019, 23 minutes after giving birth via cesarean section, her daughter Wynter passed away.
Later, NUH was charged with a crime and ordered to pay a £800,000 fine.
I am confident that [Ms Ockenden] will see to it that changes are made and that our family's heartbreak is not experienced by any other families, the speaker said.

"You're not the only one if you're worried that what you went through shouldn't have happened.
"You should speak up, talk to Donna, and work to bring about change because right now, that's what we need. ".
More parents, according to Ms. Ockenden, have worries but "haven't felt able" to contact them.
The Sikh community in Nottingham has also received a Punjabi call for parents to come forward.
It's crucial that members of our community participate in this evaluation and share their experiences and opinions, according to Harvir Kaur of the nonprofit Sikh Community and Youth Services.
The review's scope, according to Ms. Ockenden, goes beyond the Shrewsbury and Telford NHS Trust's role in the largest maternity scandal in the history of the UK.
Over 200 infant deaths there were the result of failures, according to an investigation.
