I do not and would never smack my DC , for me it isn't logical my DC will repeat behaviour if they don't understand why they shouldn't do it. How does smacking teach them why they shouldn't do the action? It doesn't, it says no in a way they can't ask any questions. Even belying the fact I spend my life trying to make my DC feel happy and safe so I don't want to undermine that by using force,it doesn't seem to be effective.
DP was smacked with wooden spoons as a child and he doesn't se either as horrifically as I do and doesn't get the irony that he says he was out of control as a 5 year old
. My ds2 is 5 , I've asked him before is there any way he could consider hitting ds2 and DP looks at me horrified and says absolutely not , he's tiny and I'm 3 times his size , I could never hit him. He doesnt see the connection.
Anyone caring for my DC (exdh , DP, mil etc) know firmly that they raise a hand , ever ,in any way to DC and the response will be nuclear, DP would be asked to leave for good and the others I would go stop contact instantly.
I have had to leave the room before when they were truly pushing buttons , but that's the point, walk away , calm down deal with it properly.
