Update on" I don't know weither to be scared or not"

First of all I just wanted to say Thank you to all who has replied to my post, it has all helped, exspecially just knowing that I am not crazy and not alone! I wanted to give you an update! Well things started getting to bad in the house. I got to the point I would get up in the morning and pack the kids up and leave and dreaded going home at the end of the day. At night I would turn on all the lights in the living room, dinning room and kitchen, and leave them on all night. I stopped going upstair at all and started using the down stairs bathroom after one night I was taking a shower and I got that same errie feeling and then something grabbed me and slung me against the wall, busting my head. But what did it for me was my son, he was playing in the front sitting room( the one that we never used) and he just start crying. That night when we got him undressed for bathtime we noticed a bite mark on his back. I thought it was my daughter. So I talked with her and she swore it wasn't her. A couple of days later he was playing in the play room off of the living room , in the floor with his blockes, and he just started screaming, I ran in and I got him calmed down and he was trying to reach his back so I lifted his shirt and saw two long scratches down his back. I couldn't blame my daughter cuz she was sitting on the couch with me when it happened. later on I caught my daughter talking to the little girl in the bathroom agian. I stopped out of the hallway and just listened and I heard my daughter telling the little girl " tell him to stop, scratching is'nt nice" so I went in and asked her who she was talking to she said it was Katie, I asked her was she talking about bubba's scratches and she said yes but Katie didn't do it it was the mean man. That night I wanted to see for myself so when everyone was sleeping in the other end of the house except my hubby but he stayed in the room with the kids. I went and sat in the bathroom ( the one that the little girl is in) and I recorded a conversation. Later me and my hubby listened to it and we couldnt believe what we heard. we moved 3 days later, we stayed in a hotel for about 3 weeks until we moved to the mountains. everything was going great until a couple of weeks after we moved here. my daughter started playing with " Katie" agian. And we have heard giggling from rooms that no one is in. My husband and I got my son to sleep one night and sat down with my daugter. We got her to call "Katie" and see if she would come talk with us. She called a couple of times then she said that she was in the room with us. We asked our daughter to tell us what Katie was saying. We asked katie did she follow us from the other house, my daughter said she said yes. We asked Why? My daughter said, she said she likes us. We asked was she the only spirit in the house? My daughter said, she said Yes. So we told her that there was a better place called Haven that she could go to, it would'nt hurt and we could find someone to help her if she wanted us to. My Daughter said, she said she doesn't want to go, she wanted to stay with us. So I said that I was going to set some rules if she wanted to stay. And told her what the rules were. My daughter said, she said that she would be good. We still hear giggles, and my daughter still talks and plays with her. She even does little stuff like moving car keys from the key ring to the counter. But over all everything has been fine. Thank you all!
