She's now 21-years-old. This is her heartbreaking story.
Tressa Middleton, now 21, from Broxburn, Scotland, gave birth to a daughter at 12 years old after being raped by her older brother, Jason, who was 16 at the time. After the birth, she became addicted to drugs and alcohol.
How it happened
Tressa explained that her brother took her to a building site, where he attacked her. She said: 'We used to go there to play on our bikes. One minute he was absolutely fine and the next everything is different.' After the incident, she noticed her body started to change.
'It was my friend who said I might be pregnant,' she said. 'She got me aside one day and said, "You might be pregnant" but I tried deny it.
'She said we better check so we got her dad to get us a pregnancy test. The next morning I did a test and it came up that I was pregnant.'
‘I never thought about terminating. I didn’t believe in abortion even at that age.'
After the birth of her daughter, her brother, who was the only person that knew who the father was, said to her...
He said: "I love you" and I said "love you too". Then he said: "No, I really love you – as a girlfriend."
'And I said: "No this can’t happen".
After the secret was out
The authorities got involved and her brother Jason was jailed in 2009 for 4 years after DNA tests proved that he was the father.
'If anything like this happens – you must speak out,' Tressa said. 'I wish I had someone to confide in when I was younger.
'I didn’t want my family to be split up, which was the main reason I didn’t tell anyone.'
The baby was eventually given up for adoption.
Miss Middleton has written a new book, Tressa: The 12-Year-Old Mum’, which she said she has dedicated to her daughter, Annie.
'I just hope one day she does forgive me.
'I know it’s going to be hard for her when she finds out her uncle is actually her dad.'
In her book, she writes about her daughter, 'You are never far from my thoughts. You are the last person I think of when I go to sleep and the first person I think of when I wake up in the morning.
'You are the beating pulse of life. In the cupboard I still keep your clothes from when you were a wee baby.
'For now I want you to know I love you and I always will.'
