Sam has no children and has no clue or business talking about it. Perhaps someone beat the fuck out of him for no reason (it happens) but spanking is just another language to get a point accross.
Anyone who has had young children knows it is nearly impossible to 'reason' with them at times, and restraint does not fix the problem, and that's not what the Bible says to do anyway.
Proverbs 23:12
Apply thine heart unto instruction, and thine ears to the words of knowledge.
Proverbs 23:13
Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.
Proverbs 23:14
Thou shalt beat him with the rod, and shalt deliver his soul from hell.
