I'm typically careful of not instilling needless fears in my toddler as I want her to be afraid of important danger and not everything and anything that might be dangerous.
We went for a vacation recently and I was being followed by 3-4 deer flies. I kept waving my hands around to shoo them away and my daughter understood that these bugs bite but has generalized this idea to ALL flies. She also got bit by something (deer fly or black fly) but I'm not sure she noticed what bit her or what happened (just saw a scab in her scalp).
This became a problem later during our vacation when she would break down at a restaurant because a (regular) fly was wandering around our food and also in the car until I managed to get the fly out. I don't mind my toddler being afraid of deer flies but being afraid of all flies is going to be hard on her! They are sort of difficult to tell apart as well so I'm not sure how I can help her out. I've tried explaining to her that they are not the same kind, that the regular flies don't bite. If one landed on my arm, I'd leave it there so she could see that I'm not scared.
I assume this fear is simply going to pass like many other things but are there any actions I can take to speed up the process?
I live in a place where most bugs are not dangerous at all; at most they will take some of your blood but there is no venom involved or direct threat to life. How do people living in places like Australia teach their toddlers to distinguish between a dangerous and a non-dangerous creature?
ETA: I was thinking some light exposure like trapping a regular fly and doing some observation involving the "protection" of a mason jar may be good for a start.
