With all the recent controversy over vaccinations, Kristen Bell is taking a hard-line stance when it comes to her children, telling friends that if they want to be around her kids they’d better have their vaccinations for whooping cough.

“When [daughter] Lincoln was born [in March 2013], the whooping cough epidemic was growing,”; Kristen told The Hollywood Reporter. “We simply said [to friends], “You have to get a whooping cough vaccination if you are going to hold our baby.”;

For Kristen and hubby Dax Shepard, who welcomed their second daughter, Delta, in December, insisting their friends be vaccinated is a no-brainer.

“It’s a very simple logic,”; she explains. “I believe in trusting doctors, not know-it-alls.”;
