Believe it or not, time outs still work if used calmly and infrequently with all media removed. My 13 yo smart mouthed me the other day. I looked at him, reminded him that it is unacceptable to speak to me that way, ever. I removed all electronics, told him I loved him but would not tolerate that attitude and sent him to his room for the rest of the night (at 6::30PM). He was stunned. He actually read, did homework and fell asleep early (I think he was tired and crabby), but I have had a sweetheart for the last week.
Another tactic that I have been using with all 3 children is that I make a point of dropping whatever I am doing when they come home, greet them with a smile, look them in their eyes and engage them in (even if it's brief) conversation about their day - having a plate of healthy tempting snacks always helps them hang out a few minutes longer with me.
It has been amazing what a diliberate smile and welcome has done to transform our house....and how I feel about them.
Good luck - be creative and be calm.
