I've two young girls, 2 and 4 years old. My two year has no fear except from being away from either myself or my wife. My 4 yr old however, has a great fear of the dark - indoors. The shadows, light from the hall etc all give her the eebie jeebies.
However, put her in the woods with a torch and a real fire and she has no fears whatsoever. All those strange noises just interest her, if anything i'm more scared of whats in the dark.
I've taught her as well as i can and will continue to do so that there is nothing to be afraid of - within reason. Up until a couple of weeks before xmas she was afraid of a big fat red bloke coming down her chimney. I carefully explained that no such person exists and she was safe in her warm cosy bedroom.
Then we were broken into, at night while we slept and the burglars scared the s**t out of her because she heard them saying Ssssh and quiet.
Now i've had to explain to her that she is safe once again, that no one will hurt her or scare her any more. All my years of teaching her to understand her fears and cope with them have been undone in one night by a pair of crack heads.
Fear in children is a good thing, it teaches them a valuable lesson in being a child and how to grow up and cope with any fears.
Last week i took her to Delamere Forest with her grandad, she refused to let go of our hands everytime someone came along. Then she did something i thought i wouldn't see - she approached a horse and carefully let it snifff her and then she patted it. She used to be afraid of horses.
So all this fear can be turned around into something good. People who smother their kids, are, in my opinion, not exactly wrong, but being over protective.
