Re-direction and time outs. By 3, they should know the basics about acceptable behaviour. Time outs are a great tool to not only give them a small time to think about what they did, but also give mom a time out to keep her cool.
My time outs work for one reason..she doesn't like to be in timeout in an area alone so that is the best thing I can do. It gets the point across and I rarely have to use it.
