S.L.
I would say you're sorry she's scared but show her it's nothing to be afraid of. Don't comfort beyond just saying you're sorry. Show her bugs outside and let her look at them. Let her feel fuzz or see you hold it and tell her it can't hurt her or you or anyone. She'll outgrow it but it all depends on how much attention she gets from this fear of everything and how much you comfort and move on. It is normal for kids to have some strange fears at certain stages but not of everything. I know some are afraid they'll go down the drain in the bathtub but usually younger than your daughter. Some of those fears are short lived if you comfort quickly and show tell them it's okay but they get over that usually pretty quickly. You don't want a super fearful child so the less said about it the better.
