Laura Gallazzi, 24, was 25 weeks pregnant when her baby baby, named Steven, at Ninewells Hospital in Dundee in March 2014.
In a new interview with BBC, Laura says that whilst the doctor was forcing her to push her baby out, before her womb had dilated to 10cm, she heard a 'pop'.
"The next word I heard was 'right push again'. And I'm thinking to myself 'why am I pushing again? I've done it'," she recalled.
"I thought I'd done it. Then a couple of minutes later, it's 'oh, you're going to be put to sleep'."
When she woke up, a nurse told Laura that her baby boy had died.
"I remember completely losing it," she said. "I was absolutely distraught. And then I blacked out again."
A doctor ended up telling Laura that Steven's head was decapitated during birth, and that it was still inside of her. She would need to have a caesarean to get it out.
After a doctor reattached his head to his body, Laura didn't want to see him at first, "because I didn't know what I was going to be looking at.
"But the doctor, she was really lovely. She said, 'it's alright'. Her words were 'I've fixed him'."
A medical tribunal ruled that Dr Laxman's decision to attempt a vaginal delivery rather than a caesarean section was mistaken and led to Steven's decapitation.
The doctor was at the end of a 24-hour split shift that night. She has since been ruled fit to practice and return to work.
