It’s a hallmark of pregnancy for many women, but “I’ve had no morning sickness,” lucky mom-to-be Autumn Reeser admits.

“I was surprised about that — I was expecting to make up excuses but I didn’t have to.”

Speaking with PEOPLE at the Badgley Mischka flagship opening in Beverly Hills, the No Ordinary Family star spilled the beans on baby — it’s a boy due in May! — and says that although she’s taking birthing classes with husband Jesse Warren, she’s going easy on the parenthood preparation books.

“I read a lot about it in the beginning and my brain was getting a little soft, so I’m back to reading classic literature,” she laughs. “I can’t read one more thing about breastfeeding!”

As her due date draws closer, Reeser, 30, is focused on baby, joking that her “spring must have” this year is a crib. One thing that has to wait until the big day? Baby’s name. “We have a few, but we are going to wait to meet him,” she says.
