Well 2 years ago now, i walked in on my step-dad raping my lil sister in her room. I panicked so i hit him in the head with a lamp, he was knocked out intill the police came. Hes in jail now he will be for another 5 years. my lil sister gets night mares she wakes up in the middle of the night screaming. She was only 6 when he raped her.

i don't know how to calm her down iv tried everything i could what should i do?
