I went to a FANTASTIC seminar today for discipline. It was given by the funniest 76 year-old-man I have ever met.
The seminar was told in a story format and engaged you in real life situations. During his storytelling, I caught myself nodding my head in agreement more than once.
He gave simple one liners to use with children over and over again to stop the arguing for good.
I highly recommend anyone with children or grandchildren to head over to the Love and Logic site to find out more tips from a man that has definitely "been there and done that".
You can request a catalogue to be shipped to your house. There are several books/CDs that are geared toward a specific parenting issue... such as doing chores. Most of the books are also available on CDs which makes for easy listening during a daily commute to and from work.
