Daren Kagasoff and Shailene Woodley

Amy and Ricky are in for a surprise when they celebrate their first Christmas together as a family on Monday's special episode of The Secret Life of the American Teenager.

When Ricky (Daren Kagasoff) tells his wife (Shailene Woodley) and son about how he and his fellow foster kids would sneak into a toy shop on Christmas Eve, the three decide to carry on the tradition. Once inside, Ethan (Michael Grant), dressed as Santa, and a very pregnant Kathy (Cierra Ramirez) decide to join the fun. But they're all taken by surprise when Kathy suddenly goes into labor.
