Danica McKellar to be a mom

Danica McKellar, who you may know as Winnie Cooper from “The Wonder Years,” is expecting her first child this fall.

McKellar, 35, appeared in a string of made-for-TV movies in the 90s before making waves in Mathematics for her books Math Doesn’t Suck and Kiss My Math, penned for girls in middle school with the hope of encouraging them in the traditionally male-friendly academic discipline. McKellar later returned to acting, appearing in movies on Lifetime and in some assorted television roles.

McKellar’s baby daddy is composer husband Mike Verta. The two met in 2001 and tied the knot in 2009. The actress is approaching the end of her first trimester, and has a new book called Hot X: Algebra Exposed coming out in the summer. She tells People that a deadline for the upcoming book initially made her reticent to confirm the pregnancy:

“When you do take the home pregnancy test, it doesn’t quite seem real,” notes the mathematician and mom-to-be. “But when you see the baby and the heartbeat on the ultrasound, it’s so incredible.”

“Me and Mike looked at each other and we could not stop the tears,” she says. “We are so happy.”
