That may be nerve-racking, not melodic, Follmer mentioned.
To assist youngsters cope, she suggests giving them a primer earlier than they encounter a loud state of affairs. For cicadas, that might imply explaining what they’re, that they don’t chew or sting, and that they’ll be right here for simply a short while.
“When one thing is uncomfortable, not having energy in that state of affairs may be very scary for lots of people, whether or not you are on the spectrum or not,” Follmer mentioned.
