the trick with time out is being consistent and not raising your voice or showing frustration with her not listening. you have to keep reminding her to sit and use a timer, if she gets up, restart the timer. explain to her that when she stays in the chair until the timer goes off then she can get out. at this point she is in control, you gotta take back that control mama. you can do it, just takes persistence.
