The last 3 times that my Fiances 6 year old daughter has come to visit she has touch my 3 year old innapropriately. The first time I thought, ok, it just exploring, talked to them both, and moved on. Then came a second time. Again she touched her inappropriately, but this time out of anger. She grabbed there because she was frustrated with my little girl who was not listening to her. She did so inside her pants and underwear. Her Father told her Mother, and he was told she would bring her to the Counselor that by the way she already has for supposive behavioral problems. Almost positive she never went, and now we have a third time. The girls were in their bathing suits playing beach. I was doing things, but had noticed extra noise so I peek in from around the corner. They were under the blanket. I asked what they were doing, and the 6 year old replied, wrestling. I told them to stop because someone could get hurt, no more ruff housing. Just a few minutes later the 6 year old told me that my 4 year olds private part was hurting. There was so much time that had passed between the second and third time that I has forgotten almost, until the 63 year old reminded me. I knew she had touched her, and asked repeatedly what had happened. The story changed several times, by both girls. At one point I told them I was going to step out side, just on the other side of the sliding glass door where I could see them, but told them I couldnt hear, and suggested they get their story straight while I got air. I listened at the door to the 6 year old telling my 4 year old what to say, listening to her say not to tell the truth because she will get in trouble. She was yelling at her. I came in and explained I had heard it all. Finally the 6 year admitted that she had touched her, why, she did not know, and I was unable to get anything else out of her. I told the two girls they needed to change in seperate room, one upstairs, and one downstairs. I kept my 4 year old downstairs. I asked her again what happened, and she said her Sister touched her inside her bathing suit, and also squeezed the inside of her legs. She heard her Sisiter coming and clammed up. The next morning when her Sisiter left I talked with my Daughter again. She then told me that they were not wrestling like they had said, but insted were playing the kissy, kissy game, which I have never heard of. She told her to play it or they wouldnt play at all. They were kissing on the lips. Again the Mother was told, and I listened to her ask her Daughter why she did what she did, and her Daughter saying she got this from various people. I listened as the Mother repeatedly told this child she is a liar, and that she is in trouble. Again she was supose to see the Counselor, and again she has not.I am extremely concerned, have two other older children, and have never been in this situation. Very unsure as to what is normal, and what is not. Please, somebody give me their thoughts. Do I have reason to be as concerned as I am?
