The six-part series will focus on two teenagers, Jamie and Laura, who meet at a Sixth Form party.
However, their lives are turned upside down when Laura discovers that she is pregnant.
Sean Verey, who has previously appeared in Skins and Doctors, has been cast as Jamie while EastEnders star Scarlett Alice Johnson will play Laura.
Deayton and Chancellor will appear as Laura's parents, while Jamie's mother and father will be played by Ideal's Ben Crompton and The Commitments star Bronagh Gallagher.
Yasmin Paige, who recently appeared in the movie Submarine, will also feature in the show alongside Dylan Edwards, who has had roles in episodes of Misfits, Ideal and Peep Show.
BBC Three's controller Zai Bennett said: "The team have assembled a brilliant cast to bring [writer] Chris Reddy's Pram Face to life and we're excited to welcome the show to BBC Three early next year."
Production on Pram Face has begun in Edinburgh and will continue until July.
