Our 6 year old is really afraid of school fire drills. He knows which day the fire drills take place and he takes noise canceling headphones that he can put on while it’s going on but it’s that initial alarm noise that really scares him. This morning he locked himself in the bathroom because he didn’t want to go to school because it’s fire drill day. What are some techniques we can try or things we can communicate to the school to make this less scary for him? He has never liked sudden loud noises.
