4yo ds I feel has signs of autism from a young age. One thing he struggles with is hand dryers, music and TV being loud. At home he will scream at me to turn it down and cover his ears, if I don't he would go into panic and run to his room.
We recently had a video from school of a music lesson and he looked uncomfortable. I asked him if he was having fun whilst watching it with him and he said no there was too much noise and it hurt his ears. (Everyone... 34 kids were shaking bells).
He has also said the noise outside at lunch is a lot too.
If he has autism would he be able to mask the struggle with noises.
