Wow! lots of interesting feedback. I have a chore chart for her as a reminder of the things she needs to do to be a good girl. I also have a big fishbowl. I bought 2 bags of big marshmallows. When her and her brother are good, finish their jobs, didn't fight etc. I put a marshmallow in it. The reverse it also true- when they are rotten I will take a marshmallow out. When the fish bowl is full they get a party. ("party" i.e. I make cupcakes, they invite a friend over and watch a movie)
I stole the idea from her kindergarten teacher who used cotton balls. When daughter came home I explained that things were going to be different around here. I took my lunch in her room and walked her through cleaning her room. I kept reminding her of the marshmallow and tried positive encouragement. I may have to do this for a week. Sit down and walk her through everything step by step. She didn't seem to mind losing her toys. I think in her mind it was less to clean. But when this weekend rolls around I'm sure she'll get pretty antsy for them.
Ok so there's an update!
