The DCs have recently taken a bit of a nose-dive with their behaviour; back chatting, fighting and arguing and generally causing riots at home (elsewhere behaviour is generally very good, and I know they have to let off steam but still). This weekend I went bezerk and banned them from the tv, dvd player, iPads, laptops, pretty much all technology. I left it open-ended and said that only when they learned to get along would they earn their lovely things back, one thing at a time. So far they've been utter shites, fighting and trying to maim each other on the sofas while I hide in the kitchen on MN. There's been no real improvement in behaviour at all, though they've played more with board games and toys they'd never normally use.
AIBU to ban them from technology like this or have I cut off my nose to spite my face? And how long do I leave it before switching on Phineas and Ferb so they leave me in peace?
