I have a child like this. If you research intensities in gifted children, you should find some things that describe your child to a T. Also look up overexcitabilities. My child is 9 and still is this way. Though she's managed to handle them better, they still exist. It's just part of who she is and how her brain is wired

. She gets freaked out by things that wouldn't bother most kids and then she worries about the "what if". We do a lot of talking and figure out what seems rational and it seems to help a lot. I think a child that is intense doesn't grow out of it, but rather learns to cope with it.
