Dear A.,
Have you heard of "Love and Logic"? It's a GREAT parenting course. The video recording titled "Love and Logic Solutions" has a section "Public Behavior" in which Jim Fay tells what to do in situations just like the one you described with your son. I happen to have this set of videos checked out of the Davis County Library right now and I watched that section yesterday.
I did a search at SLC library to see if this video is available there. No luck, although they have many other books and tapes by the Love and Logic Institute. However, no matter where you live in the state, your city/county library should be able to get these video tapes for you on an inner library loan from Davis County.
The books are good, but hearing Jim Fay's 'languaging' over and over on the videotapes really helps it sink in and teaches the brain in a way that reading a book can't. I think it's much more effective, and also takes a lot less time as you can watch while you cook dinner,etc. He is very entertaining, and watching him is also very comforting as you begin to realize that there IS a solution to your problem and it's not nearly as difficult as you had imagined. Immediately, you feel supported and not so alone.
Also, depending on where you live, various county agencies offer free, or inexpensive, Parenting with Love and Logic courses. Also, I just checked the L&L website and there is a 1-day conference with Jim Fay in SLC on March 10. You can also get a lot of support from the website and find many of their books/tapes on Amazon and eBay. I would always recommend either video or audio tape, as as using the program successfully is dependent on using certain language effectively. You'll understand what I mean when you see the videos.
I was a single mother of 3 for many years. I wish that I had known about L&L during those years. I know it would have made all of our lives much easier, as it would have helped me be a much more effective parent. My children are grown now and doing very well. I am working as an educational consultant to help teachers with problems in their classrooms. L&L principles hold true for all ages and all situations, home or classroom. The best situation is parents and teachers working together with L&L.
I hope this is a help to you. Feel free to email me if you would like.
Best wishes,
S.
