Gladman, who is now a barrister, says she didn't want to talk about her ordeal on Big Brother.
"I felt it was too deep and too real a trauma to be discussed on something as frivolous as a reality TV show," she says. "But the producers knew about it. They obviously wanted to get the story out of me."
Gladman is on the verge of tears in the ABC show as she recalls the shocking stunt that producers asked her to take part in.
"So they sat us in the lounge room and then two-by-two we went into the diary room. The first couple went in and came out and they were carrying a plastic robot baby and it was sort of making crying noises and stuff.
"I just … the blood drained from my face. And I said, 'You've done this deliberately and I want to leave the house.' And they said, 'You can't leave. You have to stay and you have to tell your story.'
"That's how they manipulated me, by asking me to look after a plastic baby in circumstances where I'd lost my own baby 18 months before."
Gladman broke down in the house and refused to take part in the challenge which was described by the media at the time as "a new low for Big Brother".
Gladman's mother, Anne Gladman, slammed the show's producers in the press and described the stunt as "sadistic".
Even Big Brother's executive producer at the time, Kris Noble, admitted it was a mistake.
"Knowing the way it affected her now, we should never have done it," Noble told The Daily Telegraph after the incident.
"No one wants to see someone in that situation. But we had talked to her about the baby and she said she was completely over it.
"But in hindsight we should have been a bit more sensitive. It was hard seeing her react like that because you grow attached to everyone and don't want to see any of them hurting."
