My JW Mother used spanking as stress relief. It made her feel better to hit her kids wherever she could get them. She punched me in the face on two occasions and picked up a set of drawers and threw it at myself and my Sister.
At anytime, anywhere she could go on the attack, for any reason. My parents firmly believed that Jehovah required them to 'belt' us whenever they thought it was needed. When witlesses raised an eyebrow to her behaviour she would brag that it was deserved punishment.
Public humiliation was a favorite of my Mothers, the more people watching, the better.
By the time my little sister was born 18 yrs after me, I had threatened to call the police on many occasions on her violence, I really wish I did.
One family in our cong when I was a kid would sit with their four kids right in the front row every meeting and each meeting there would be at least one face slapped. The only way they punished their kids at the meetings was a very hard slap to the face in front of everyone. I remember looking around me and seeing other witlesses wince as they saw and heard the slap to the face. It was quite a distraction to everyone as we sat and watched the kids face turn red with a handprint.
My two kids have both turned out lovely and almost never smacked, only punished and had boundries set for them. Im a big believer in sitting down and talking about things, reasoning with kids was never my parents forte. I have NEVER smacked either of my boys out of anger.
A sharp smack on the hand has been helpful when the kids were little and doing dangerous things like playing with powerpoints and no other reasoning would work. But generally I dont believe in smacking children as it is open to abuse by bad parents like mine who think God expects them to belt their kids.
