Jessica Alba worries her newborn daughter HONOR will contract a virus - because she was always sick as a child.
The Fantastic Four star went so far as to study her mother's pregnancy diet, and eat everything she didn't - in a bid to make sure her child was healthy.
She even made sure she took different medications.
Alba explains, "I was always being sent home sick from school and sometimes I was out for weeks. If I got a cold, I automatically got pneumonia. Sometimes it was so bad I was in the hospital.
"I've come to think that perhaps I was a product of my environment or the vaccines, or something my mother took when she was pregnant."
