every night for the past couple of months now my daughter seems to start an arguement with her sister or get moody with me and my partner befor going to bed, this then turns into her crying throwing things or hitting herself, sometimes she says she misses my x partner and gets very angry with me over this. shes not allowed to see my x partner due to legal issues, ive tried star charts timeout and one on one time but she just plays up more any ideas in how i can help her.
