Scared of needles? Too bad. Kristen Bell has forbidden people who aren’t vaccinated from meeting her mini-mes. Bell recently told The Hollywood Reporter, “When Lincoln was born, the whooping cough epidemic was growing, and before she was 2 months old, we simply said to friends, ‘You have to get a whooping cough vaccination if you are going to hold our baby.'” Bell is doing the same thing for her daughter Delta, who was born Dec. 19. The Frozen actress added, “It’s a very simple logic: I believe in trusting doctors, not know-it-alls.” On a lighter note, House of Lies actress appeared on Jimmy Kimmel Live! Tuesday and opened up about raising 22-month-old Lincoln and her 8-week-old Delta with husband, Parenthood star Dax Shepard.
