I moved in with my fincee three years ago. He has a Daughter, 7years old, he has raised her since she was 4 when her mother left. When I first moved in she listened to everything I asked of her. Even over her father. Recently since she started speaking with her mother on the phone her behavior has taken a turn for the worst. She refuses to listen to me at all, disregaurding everything I ask of her, arguing with me comstantly, trying to embarress me in public situations, and now as of today startied acting out in school. She will be all sweet and momy this mommy that, until i tell her no about something. At which point she will whine, argue, yell, tell me no, and Im not her mother. I have spoken with her father about the issue at hand but its almost as if he dont believe me. I have almost completly shut down due to stressing about this behavior. I dont like to spank her because he has never really displayed physical disipline. I have grounded her, taken her toys away, she has lost privledges, written sentances, stood in the corner, did wall sits, assined chores, you name it I have tried it more than once. She responds by stomping off into her room and breaking her things in rebellion. when its just her and her dad she listens to him and occupies herself. WHen she is with me (majority of the time he works all day into the evening) she expects me to entertain her constantly, and refuses to do her chores, or homework, geting into shower etc. its literaly to the point where I cant make her do anything she will not listen. Then goes to her friends or others we know saying I am mean to her, and dont listen to her at all. I realize that step-families require more effort and are challenging to blend, but sometimes I feel I am the only one trying to make it work, and keep her safe and raise her correctly. What can I do to make her respect me again? and What chores are approperate for her age? All I ask now Is for her to clean her own room put clean laundry away, and pick up after herself after meals, showers, or activities. IS that too much? And what disipline ideas could i try now? please help before I throw in the towel!!
