"I gave birth on 16 November 2014 to a beautiful, beautiful little girl called Layla," she's told Newsbeat.
"She was 9lb 9oz.
"I got to spend as much time with her [as I wanted], even though I look back now and I feel like the time that I had with her wasn't enough."
Rosie Felton, 23, from Staffordshire has two daughters - Ella-Rose, who is nine weeks old, and her big sister Layla, who was born two years earlier. Layla was stillborn.
Telling Newsbeat the story of the days and hours leading up to Layla's birth, she says: "I feel like my heart's being pulled out but in a way, I find it easier to talk about it every time."
In parliament Conservative MP Antoinette Sandbach, who lost her five-day-old son in 2009, described this as the "most devastating" event a parent can suffer.
Each year about 3,500 babies in the UK are stillborn, defined as being born with no signs of life after 24 completed weeks of pregnancy.
Another 2,000 babies die within the first four weeks of their lives.
Rosie says she thinks it's important for parents to feel able to talk about the babies they have lost.
"I know she's passed away but I should never forget her," she says.
"I know she's here with me in spirit and I really, really believe that. The way I've been able to cope is to talk about my daughter."
But other people have struggled to have a conversation with Rosie, after hearing about what happened to her and Layla.
"Some people listen. Some people, you feel like you can't talk to them about it because they feel awkward," she explains.
"For instance, when I went back to work after my maternity leave I was working in a supermarket and everyone that I was seeing said, 'You're back so soon. How's the baby?'
"Some people felt really sorry for you and you had to then comfort them.
"Some people would just avoid you. And then some people just didn't know what to say."
Rosie says she had "great support" from her family. Her mum had a pillow made with Layla's picture on it, as a way for Rosie to remember her daughter.
She says charities and online communities made up of parents who have been through similar experiences have also been really helpful.
"When people ask me about her, obviously I still get that lump in my throat," Rosie says.
"But I want people to talk about her. I want her to be remembered forever."
