Have them remain grounded and revoke further privileges (no more games, no more chocolate, etc. etc. you can't run out of these really) eventually they will be desperate to get out of that situation themselves, which is better than not even being convinced, just coerced because a spank physically hurts.
Some therapists now say that a grounding longer than 2 weeks becomes ineffective.
My wifes nephew kept havign issues with porn, constantly stealing other people devices and looking up porn on them. You could imagine my wifes face when she took her daughter to cheerleading practice and her daughter pulled out her ipod to show off pictures of her cat and there was dozens of porn pics that all these 8 year old girls saw. I struggled with the boy for 5 years to deal with his rampant porn issue that was causing major problems within the family.
Try to tell me that these kids do not need a spank...
IIRC. The kid in the second video was caught keying cars or something like that. The original video is much longer and it shows the kid swearing at everyone and absolutely freaking out. Yes, the parents are terrible as well and need to get handed some punishment too. But many times the child has just gotten too out of control no matter how good of a job the parent did.
Some people go around their whole life talking shit to people and thinking "Yeah, you can't do shit to me" and they keep instigating people. It isn't until someone finally snaps and punching them in the mouth do they finally smarten the hell up. I know when I was a kid I was quite the little shit. I certainly needed my ass handed to me, and I would say that I have learned quite well from those lessons and never repeated those behaviors. My father has whooped my ass multiple times when I did some rather terrible things, and I deserved it, but I also learned it.
I feel spanking a child is alright when it is used as a last measure.
Not every child responds well to being spanked like I did. Some children are just sociopaths and things like that doesn't matter to them and they don't give a damn and will do whatever they want... and then end up in prison later on in life.
