Whenever I take my 3.5-year-old nephew to some unknown place or somewhere he is not comfortable, he puts his fingers in his ears as if he wants to avoid a loud noise.
Even if I take him to some dark place he does the same thing. Initially I saw him putting his fingers in his ears while traveling by train, then he started doing the same thing in the car, bus, even in my home when he was watching a horror movie.
I want to know how to come over this situation.
