Speaking with the Daily Mail, Gillian Relf, 69, said that the difficulties she faces while raising a son with Down's Syndrome have proven too challenging.
She said: "This is my son, whom I've loved, nurtured and defended for nearly half a century, but if I could go back in time, I would abort him in an instant."
Gillian and husband Roy are childhood sweethearts, who are now looking forward to celebrating their golden anniversary.
But, despite her first pregnancy being 'easy', she admits that her second pregnancy was difficult; she had a sixth sense that there was something wrong with her baby.
When Stephen was born, Gillian immediately knew that he was (in her words) a 'mongol baby' - and she immediately began questioning whether she could have caused the disability.
And, while many assumed that she would grow to accept her son's disability over time, Gillian openly admits that this has not been the case.

"While I do love my son, and am fiercely protective of him, I know our lives would have been happier and far less complicated if he had never been born. I do wish I'd had an abortion. I wish it every day.
"If he had not been born, I'd have probably gone on to have another baby, we would have had a normal family life and Andrew [her eldest son] would have the comfort, rather than the responsibility, of a sibling, after we're gone."
Gillian admitted that her mental health suffered after having Stephen, forcing her to attend regular counselling sessions.
And, despite her 'incontinent and uncommunicative' son living in sheltered accommodation in Kent with two other women who have Down's - where they have 24 hour support from carers - Gillian has appealed to all pregnant mothers not make the same mistake she did.
"Do what is right for you and your family."
