Tonight I put my kids to bed and I was washing some dishes and my youngest Gabriella (she is 3) comes donwstairs and says Zoey ( she is 7) choked me..there was a red mark on her neck...I went up stairs and Zoey was hiding and I asked her what did you do to your sister..she said I gave her a hug..I told her no a hug doesnt leave a red mark on someones neck..I asked her did you choke your sister...she didnt say anything..I told her you never ever do that to someone and asked her do you knwo what can happen to someone if you choke them..she said no..I told her you can kill someone by choking them hard enough..I didnt yell at her I talked to her calmly..and I put Gabriella in her bed and Zoey says then maybe she should have listen to it so loud ( the toy Gabriella was playing with) I told her that dont matter you still dont choke your sister and I told her if she does something that makes you mad you come and tell me not hurt your sister. I also told her seh was grounded for the week end and not allowed to go play at the mall ( there is a kids play area at the mall the kids like to play at) I am really bother by this..it is the first time Zoey has done that to Gabriella..she hits Gabriella and kicks Gabriella and she is mean to Gabriella..I am sure Gabriella isnt an angel when Zoey gets mad at Gabriella but I dont know how many times I have explained to her why she shouldnt do that stuff to Gabriella and how it can hurt Gabriella if she keeps doing it. Do I talk to her guidence counsler at school about what I can do..Any advice would be good before it gets worse. I never choked any of my sisters even though I got mad enough at them but never did it. none of my sisters ever did that to eachother..I honestly am at a blank at what to do with her. I dont want to just ignore it and it gets worse and Zoey just starts being an aggressive child.
