I have 2 dds aged 10&13
They've never been particularly close but in the last 6 months their relationship has deteriorated
Everything my 10 yo does seems to wind up my 13 yo from breathing to the programs she watches on tv
Sometimes the winding up is deliberate, sometimes it's just existing
My 13yo is getting increasingly verbally aggressive towards her sister
Punishments don't work such as taking her phone away -it just escalates things
If I tell her she can't go out she doesn't care
They both have their own rooms but both prefer to be in the living room
Sometimes they get along fine, will laugh at YouTube together etc but the number of hostile incidents is increasing
Do I just ride it out hoping they both come out of their teenage years alive or can I do something about this?
