To help pursuade our child to be well behaved we try all sorts. We threaten her with being grounded, no treats, bed early and from Sept we start reminding her she needs to stay on Santas good list. All these things work to a degree. We have other methods too but I'm generalising here.
When I think back to my childhood I was threatened with the fact that Jehovah was always watching me and I could be destroyed at Armageddon.
So my child has the fear that she won't get treats and gifts and I was always in fear of a horrible death.
