 When I grow up, I want to be a doctor because that's a really important job. I would help kids get better and make everything super fun. I'd have a cool waiting room with games, toys, and a huge TV. If your child is sick over and over again, it could be PI, a serious defect of the immune system. Early testing gives children a chance to dream. And I'll give every kid a cherry lollipop because that's the best flavor.
