Little Miss Sunshine's Abigail Breslin is one, too.

If your kid always thinks she's sick, you're not alone. "I'm a hypochondriac," 12-year-old Abigail Breslin told Los Angeles magazine. "I'm not allowed to watch medical TV shows. [Once], I was worried that I was going to step on glass, so I wore shoes even in my bed...I thought I had bird flu, so for a long time I wouldn't go near any birds."
And, as she filmed Nim's Island in Australia, the New York Post reports she feared she'd been bitten by a poisonous spider. "My best friend on the set was the medic," Breslin says.

Pediatrician and momlogic contributor Dr. Cara Natterson says, "Being a true hypochondriac, to the point that it limits how you live your life, is fairly uncommon at any age. But hypochondriacal thoughts--like being worried that you could catch a cold when hugging someone hello or getting nervous that a new cream will make you itch--are not uncommon at all. Parents should take their child's concerns seriously, but as soon as it is clear that an issue is not real, reassurance is best. If you mock or punish your child for having these thoughts, it doesn't stop the thoughts, but only stops your child from telling you. Remember the boy who cried wolf? Eventually, if something really is wrong, a parent doesn't want to miss it."
