Hi
Brief background. DD is 3 yrs 7 mo old. I have a 8.5 mo old DS. She is a wonderful girl, bright and clever, very loving and caring. She loves her brother, we've had a bit of jealousy issues, but nothing major. She is aware how much we love her and we have instilled in her values about family etc.
She has started to hit me. Over nothing. Quick example, last night I got her out of the bath. She didn't want to get out as she was playing but it was time. She slapped me. Punched me in the stomach then started kicking me. The look on her face, it was like she'd been possessed. I didn't know what to do. Said calmly, "we don't hit, kick or punch in this house, it's naughty". She did it again. I picked her up, kicking and screaming, wrapped her in a towel and carried her into her room, put her on her bed, told her the same message and shut the door. Went back to DS to bath him, fed him and then went back in. She just sat on the bed sobbing. I dryed her hair, got her PJs on (well half on as she threw her top across room). I ended up leaving her as she wouldn't listen. every time I tried to talk she made a screaching noise.
Her daddy came home then and spoke with her while I put DS down in cot. She knew she had been naughty and said that "mummy was sad because [name] had slapped her and kicked her" and she said she was "naughty".
This has happened a few times. I have also caught her trying to be violent to her brother, kicking him, dragging him around. Straight on naughty step with the same message.
What else can I do - open to suggestions. I don't want to start threatening no santa etc. I have tried to remain calm but this morning I was in floods of tears as my beautiful girl has turned into a violent monster. She is not violent out of the house, ie at nursery, she is an angel with everyone apart from me/her brother/sometimes her daddy. Help me as I'm not sure what to do. Thanks in advance.
