My niece aged 7 was caught having oral sex with another 7 year old. Also a seven year old girl was caught putting toilet paper up my nieces butt. She began acting out sexual things with dolls. Fast forward age 10 a 9 year old cousin bribed my 10 year old niece into playing a humping game. My niece then humped her much younger sister and is sexually acting out with animals. Age 14 my niece is goosing younger sister. Did the things she went through qualify as sexual abuse or are they normal childhood play. If they are just childhood play. Why is my niece acting out?
