to start, Kids are just jitterish from the start. So yes, it is normal to feel fear as a kid. I think most kids are too immature to understand fear usually. (maybe 3-7 year olds.) But it still happens. When i was a kid I used to worry about my families safety. Its a big thing kids worry about. I was worried that i would accidentally sleep on my hound when i was getting from school. If your scared as a kid you usually get comforted by your parents. Usually the mom since dads are typically not too well with sad or emotional children. I am definitely a worry worm for my family. When i was around 7 or 8 my mother broke her ankle at a party when we were celebrating July 4th. It was horrible. I couldnt do enough for her, I felt like I wasn't good enough for her. I Could not sleep knowing that she was uncomfortable. Soon enough I realized that i shouldn't worry. And that she was in good hands. I also noticed that it wouldnt do any good to worry about her as she was already stressed. When she came home, she was all better. I learned to trust the hospital as they have all the knowledge they need to take care of everybody.
