“My first pregnancy was beautiful, easy and happy. I was floating, eating everything I wanted,” she tells PEOPLE for this week’s issue. “I thought, ‘Great, I get to feel that again.’ “
But around her fifth week, Christina began suffering from bouts of intense nausea and vomiting. “It’s just a terrible feeling,” she laments. “I would be running to the bathroom and David would be holding my hair.”

The morning sickness — which Christina actually experienced at night — “really caused a lot of problems for me as a mom,” she says.
“I couldn’t take the kids to school or put [the couple’s older son Charlie West, 3] to bed,” Christina adds. “I was just sick and in bed all the time. I don’t think I brushed my teeth for a week because I was so bedridden and uncomfortable.”

Christina finally found relief when her doctor prescribed Diclegis, the first FDA-approved medication to treat morning sickness (she’s since become a spokesperson). Thanks to the medication, she was able to resume her life — and, in particular, return to family dinners.
“I’m from Arkansas,” she says. “We do all the southern stuff — fried okra, fried chicken, dumplings.”
“We’ve got a teenager, a toddler and a newborn,” David says, laughing. “It’s a crazy household.”
