hello, help please. my normally mainly nice 12 yr old is getting really stroppy. i need better ways of disciplining him while taking into account that: his father and i are separating, he has had to change schools, countries, friends, houses everything in May last year (after already changing them all 2 yrs ago) due to emergency move back to france from peru because his 9 yr old brother was diagnosed with leukemia. the worst so far has been him - the 12 yr old - telling me to shut up (which his dad told me for years) and also, when i told him about the separation, saying 'fuck you and fuck dad'. currently we are doing a week without computer as punishment for the shut up (i was cross/hurt about the fuck you and said so, but mainly let it slide because it happened the day I told both children about the separation, and so far, has not happened since. btw: the 9 yr old said 'oh'). thank you.
