DD s 13. DP has a 4 year old DD who stays with us but doesn't live with us.
We had a lot of stress with DP's ex and have just been through a massive and very stressful court case. DD was aware of how difficult and stressful it was.
DD has a habit of saying very spiteful things when she is annoyed or upset. So yesterday she told DP's DD that her mother was dead......
DP's DD asked me if it was true, luckily she doesn't really understand the concept and I was able to explain that of course she's not and that she's absolutely fine.
DP was furious with my DD (as was I). DP didn't shout at her, he left it for me to deal with her which i was glad of. DD then stormed to the bottom of the garden and howled loudly. DP had to carry her into the house at 9pm (sent straight to her room) where she drew all over her face and arms in red pen and wrote him a note saying how horrible he is and he makes her want to kill herself and has done many times....
She is a bit sheepish and quiet today. DP is still very angry. He's asked how I plan to punish her.
She's had therapy before after her father left to live 200 miles away and start a new family a year ago. She was very upset about this and had lots of rages where she'd threaten to hurt herself or jump out of a window. She has calmed down a lot since though.
