Faye Windass, played by Ellie Leach, will apparently become the youngest parent in soap's history - but Coronation Street have been warned by the Family Education trust that their story could be 'damaging' to impressionable children.
"[This could be] damaging to impressionable children"
Norman Wells, speaking on behalf of the trust, said: "One of the problems of giving prominence in a soap to life experiences that are extremely rare is that it can distort people's perception of reality and give the impression that such experiences are far more common than they really are.
"In spite of the fact that teenage pregnancy rates in the UK are high compared with many other parts of Western Europe, they are still thankfully rare - and pregnancies in 12 year-old girls are much, much rarer still.
"Scriptwriters and production companies need to take great care that in their desperation to attract high viewer ratings they do not normalise behaviour that is both illegal and damaging to impressionable children."
The ITV soap is understood to be developing the new plot for later this year.
A Coronation Street source told The Sun: "This is bound to be a controversial storyline but the programme has a history of handling difficult subject matters in a sensitive and considerate way."
It has not yet been revealed who will be the father of the young mum's baby.
Faye Windass will join a long line of young soap mums, including Demi Miller, who was 13-years-old when she became pregnant in EastEnders, Sarah-Louise Platt, who gave birth in Coronation Street at the age of 13, and Amber Sharpe in Hollyoaks.
Teen character Cindy Beale in EastEnders is also expecting her first child, at the (relatively) more mature age of 15.
