Over the years, my wife and I opened our home to 104 foster children. The 9 year old boy who came to us in the early 70's with scars and welts from being beat with a belt... His was the first text to my wife on Mothers Day. Retired, himself, now in Tennessee. Calls "Mom" at least once/month and always remembers her birthday and Mothers Day. He didn't deserve being physically and emotionally scarred for life. Or... the siblings, 4 and 5 years old. The 5-year old boy was deaf in one ear from being hit so hard it damaged his eardrum. His 4-year old sister had scars all over her back from lit cigarettes being used as discipline enforcement. Neither deserved the physical and emotional damage they will carry for life. Even the young lady I walked down the aisle in 1990. She had been physically, sexually, and emotionally damaged by her biological father. She found, with us, that life could be better. She and her husband are still married, both their kids have graduated college and they have done well.
Our own three kids, of course, had times their actions challenged us. NEVER did we use corporal punishment. NEVER would we hit a child. All three have been successful in their careers and all three are married to their first spouses... one of the girls just celebrated their 25th wedding anniversary this week. I just cannot understand the "need" to inflict physical pain on a child to get a message through to them.
