A mum is planning to freeze her eggs so that her four year-old daughter can have children one day. It will mean she will effectively become a grandmother to her own child.
Little Libby Dye suffers from a condition that means she will almost certainly be infertile when she grows up.
But her mum Jenna is determined that her little girl will have the same chance of becoming a mother that she had.
Jenna, 28, told The Mirror: "The longer I thought about it, the heavier it weighed on my mind.
"I became depressed, haunted by the idea that Libby would never be able to have children of her own, never be able to pass on her genes.
"When I realised how much this abnormality would affect her life, denying her the joy of becoming a parent, I got a sinking feeling which wouldn't go away."
Libby was one of around 170 girls born in 2008 with Turners Syndrome, a chromosomal abnormality that affects physical appearance and in nearly all cases causes infertility.
But now, after tackling scepticism and doubt from the consultants who told her about Libby's condition, Jenna is preparing to have the first of her eggs frozen, all with the support of husband Stuart, 30, and six-year-old son, Alfie.
"Even when I was very small, I dreamed of starting a family of my own," Jenna said.
"So when Alfie was born, it felt as if my life was truly beginning. When Libby came along I believed our family was complete.
"But even from the first days, we were concerned about her health. She didn't feed properly, she seemed sleepy all the time and her eyes were puffy."
After tests, Libby's parents were told the news about their little girl's condition – and the implications for her later life.
So Jenna made the decision to freeze and store her own eggs so that when her daughter reached a point where she wanted to have children, she could have them implanted in her womb.
"Me and Stuart don't want any more children and Libby doesn't have any sisters," said Jenna.
"Who knows what circumstances she'll find herself in when she's older?
"I thought: 'I'm her mum, it's up to me'. This was something I could do for her now."
It took months of testing and interviews to get doctors to agree to the plan, but then, in November last year, she was given the news she had hoped for.
Her eggs were a good match for Libby and the procedure could go ahead.
Should Libby decide to use her mum's eggs, Libby's future partner's sperm will be used to fertilise them in a laboratory before the embryos are placed within Libby's womb, which is completely healthy.
"Technically, if Libby decides to use my eggs one day, she will be having my biological offspring," said Jenna.
My grandaughter will also be my daughter. Libby's daughter will also be her sister, genetically speaking.
"What I've made clear to everyone who's asked is that I don't have any desire to have more children - two is enough for me.
"I would love to be a grandmother, but it's Libby who I'm thinking about before anyone else."
What an amazing story of a mother's love.
