never say never, but i cant imagine hitting a child of mine. i dont have a problem with it, my parents hit me when i was being a shit, but i dont think teaching your child to do the right thing with violence is optimal.
id imagine the mentality behind hitting kids is you do it cause they arent old enough to understand why what they are doing is wrong (i hope thats the mentality, cause otherwise anyone who endorses beating kids surely must endorse slapping the wife around). the problem here is if youre hitting them at that kind of a developmental age you are drilling it in their heads that violence solves problems,and that does more harm in the long run than short term good (ie less noise, mess, whatever the kid was doing that caused you to hit him)
id much rather find another way to hurt his pride/punish him physically, like make him do 1000 situps, clean the toilets etc...
