Okay, so most people in today's world think it is improper to spank children, so I have tried other methods to control my son when he has one of 'those moments' in public.
One that I found effective is for me to just take my son, Landon, for a car ride and talk.
Some say it's the vibration from the car, others say it's the time away from any distractions such as videos, Video Games, Computer, etc. Either way, my son usually calms down and stops misbehaving after our car ride together. The eye to eye contact I keep with him on this ride really seems to help a lot too.
I've included a photo below of one of my sessions with my son, in case you would like to use the technique. I hope this helps someone out there...
