Questions on Mealtime Problems

1. First of all, I want to thank you from the bottom of my heart for all of the wonderful books you have written. I recently initiated positive discipline with my 9 year old son who was truly spiraling out of control with anger and sadness. I realized that much of the problem (besides being from a divorced family and now two parents that have remarried) had been helped along by creating power struggles, doling out punishments like candy and other "negative" forms of discipline. I have to say that within days of initiating positive discipline, my son has become a new person. He continues to blossom every day into a happy child who is taking more responsibility for his behavior and generally more in control of his angry outbursts. Thank you, thank you, thank you! Anyway, I have several areas of uncertainty with regard to natural and logical consequences. My question today has to do with table manners. My son has horrendous table manners ranging from eating with his fingers, to burping and other expression of gas!! He thinks it is funny and it is particularly discouraging when he does it in public. We have a party to go to this weekend and more than likely he will do something that would not be considered "polite" at a dinner table. I have tried everything you can think of in terms of punishment and power struggles over the years, but now I am at a loss as to how to deal with this positively. Thank you in advance for your response. Happy New Year, Shelly

4. Our main trouble lately is meal time. We aren't the sort to force our three-year-old child to sit and eat (I don't want to make meals unpleasant)
