S.L.
I have 9 kids and I used this for all of them. We have a couch that is the initial time out zone( we need a couch because sometimes there are two or three in time out) Anyone who does not sit a quiet a time out and starts to yell or get up, moves on to the next phase of time out. They ared moved to the corner. If they cant be still and serve their time there, we have another small couch in a room of solitude. They really dont like to go to that couch, and have also learned that they dont like the corner. They now prefer the couch, and most of the time, they sit their time out without any trouble. See the thing is this...if they get moved to the corner, it lengthens their time out...they serve time there before they are ALLOWED to go back to the time out couch. Then they learn that sitting shorter on the time out couch is better and shorter for them, and they behave on the couch the first time.
Keep up the hard work. Just be consitent. And dont worry about explaining too much what they did wrong. They generally know. At 2/12 they are smart enough to know what you allow and dont allow. Just remember, they are not little adults and cannot be reasoned with. They are simply little wild animals who need to be trained LOLOL
