Conflict resolution

Our first attempt at structured conflict resolution.  My girls love one another so much and they play together ALL the time.  However, they are girls and so they bicker.  It is getting to where they are getting a tad aggressive (E more so than C) so I decided to try something.  Today I got out their two school chairs (the shopping cart was brothers attempt to be a part of this).  I made them sit across from one another.  I told E to say something she liked about C.  She was still mad and refused.  I told C to do the same thing.  She immediately said sorry for what she had done. (Praised her for that but told her I wanted something different from her).  She kept referring to what she liked to do with E.  I tried to get her to understand and by then E was laughing so then she was willing to try to give an example to C.  She said she liked C's dress. (not quite what I was going for but they were positive statements so the point was being made).  I asked them to do that a few more times and by then the anger had dissipated and they resumed playing nicely.  Mission accomplished (this time LOL) 

*update* this still works a month later. Yes they still fight but this method breaks the tension. Yay
