I think as long as they are warned that a spanking is coming for certain behaviors, and then the spanking is given as punishment instead of some sort of revenge, then the child will learn boundaries. How you regulate parents that are out of their freakin minds is beyond me, but not allowing corporal punishment gets you the brats we have today.
We were on a three ticket limit and then he goes into time out. (I never thought it would work. It does) We’ve now gone straight to timeout. If misbehavior continues it’s up to the room - and it may be a while. If boy mouths-off to Mom (big no-no) He goes to the woodshed for a talk. We employ the Andy Griffith method, lol.
