Hello, I'm not a mother I'm a big sister (18 years old), the eldest daughter, and I wanted the opinion of a mother on this subject. Today my little sister (10 years old) saw the dead body of one of our neighbors, he unfortunately fell down the stairs and she's the first one- along with the man's daughter and my own mother, who saw him dead. She was there too when the neighbor's wife was called, and you can guess that she was screaming and crying her heart out. She really liked this neighbor, they'd high five every morning and he was overall very kind to everyone.
After the police, investigators, and all the other neighbors were called, my little sister and mother came back home, and unfortunately my mother's coping mechanism is to avoid thinking about it, thus she assumes it's good for my little sister. Whenever my little sister starts crying and talking about it, my mother says "Come on now, forget about it, okay?". I pointed out that it's unhealthy and I let my little sister vent to me. Is it the right thing to do? Should I do something else, or more? How can I help her?
