It’s a Bachelor baby!

Jason and Molly Malaney Mesnick are expecting their first child together in late March, the couple tell PEOPLE exclusively.

“Our family is getting a little bit bigger!” Molly, 28, proudly declares. “I’m into my second trimester and I feel really good.”

The couple met on season 13 of the ABC reality dating show and endured intense media scrutiny over their union. But the criticism died down after the two settled down in Seattle and got engaged.

The new addition will join Ty, Jason’s 7-year-old son from his first marriage.

“He’s been so excited to be a big brother,” Jason says, explaining that the couple — who wed in February 2010 — decided to inform the second-grader of his new sibling via a family game of hangman.

“The answer was ‘Tyler is going to be a big brother,'” Jason, 36, shares. “He’s been asking me for years. He’s always wanted to be a big brother. So we played the game and he looked at Molly and I and said ‘Really?’ Molly made him a t-shirt that says ‘Big Brother’ on it and he’s really proud. He wore it to school.”
