My son (2.5 + Y) seems to get frightened looking at the windows specially during evening or night. We stay in the 3rd floor of a residential complex, which is surrounded by quite a few trees outside. He sometimes gets so scared that he moves from our bedroom to my parents bedroom. This has become quite frequent specially past 2-weeks & even presence of me & my wife could not convince him. Any tips how to get rid of his fear? We have bright lights in the room & no scary item inside as well.
