Hi J.,
I am so touched by your bio, about having twins with one in heaven - I'm thankful you believe in Heaven and am certain you've been teaching your son where his brother is! Good job!
When our first two kids were your son's age, someone recommended the books and cassettes, "Love and Logic Parenting" by Jim Faye and Foster Kline. You'll find them on the web. They encourage parents to teach children the consequences for their actions, from preschooler age up to teenagers. Their stories are funny, too.
I also read a lot of Dr. James Dobson's material and learned how kids actually enjoy getting angry reactions from their parents, as it somehow makes the disobedient kid feel like he/she is in control. Once I learned this, it seemed I was always seeing a kid controlling his/her parent in a grocery store, or wherever else, and the parent ended up being very embarrassed and giving into the child, which just fueled the child's bad behavior. Very recently, my husband and I took our kids to a museum and our 4 1/2 year old daughter cried and cried because we wouldn't buy her a stuffed animal. But we did not give in to her, and even though we were embarrassed, we got through it.
Putting what I read into action has worked, but of course I still mess up. I just have to re-focus when the heat is on, but if I take the time to pray and think, God always tells me what to do.
Sincerely,
C. Phillips
