I think it is normal for people to be extremely afraid of illness and death at a certain age and try to escape. At least from what you described, I don't think it's a problem. I just pay attention to my health and take preventive measures. A lot of older people do. If the child discourages at this time, it will make her more nervous and even lost. Why not try to put yourself in her shoes? Let her feel that everyone is thinking about her health and longevity and caring about her. Maybe she can relax more. Just a personal opinion.
