I was regularly smacked as a child. I don't remember specific incidents, except one time when my father stood at the bottom of the stairs, bellowed "get up those stairs" & we had to run fast before he could swipe us! My parents were great believers in control & we were terrified of them. Worse than smacking was The Look across a room, especially if we were out, & the lull as we got into the car/closed the front door knowing that the dressing-down was coming. Our more serious lapses were always d/w by a severe talking to, which was MUCH MUCH worse than the smack.
My mother also used to do the repetitive criticism thing, which is also far worse than a smack & stays with you well into adulthood. (What do I mean "used to"? She still does it!!! )
I smacked my children because I didn't know how else to deal with them. TBH, I'm not convinced now that smacking is a good thing, but at the time it worked. I wonder whether those real anti-smackers have particularly good children. I say this because I had a "friend" who was very virtuous because she didn't believe in smacking her perfect little girl who never put a foot wrong. When her second arrived & was a total whirlwind she rethought her views entirely.. With mine I regularly smacked DD & DS2, very rarely DS1, & didn't raise hand or voice to DS3 until he was 6 because he didn't need it! Helped that I didn't look after DS3 full-time because I'd gone back to work/uni, & FIL & nursery/playgroup had him most of the time.
What do those of you who don't ever smack do with a child of 2-3 years old who knows that we never go in the car without doing up our car seat straps, but also knows that we are running late & haven't got time to just all sit in the car because we have to get big sister to school, & keeps undoing them? (Not being funny, genuinely interested). Not an option to have a long-winded discussion, nor to give in & say "it doesn't matter", because in that situation it really does matter. Nor is it an option to say we'll stop the car & all sit here until you stop undoing it, which we used to do on endless other trips, or "we won't go then". (School not walking distance & no-one available for taking child to school/babysitting others).
My own children say they do not remember being smacked & I can't remember when they last were. (Now 18, 16, 14 & 12). It doesn't seem to have done them any harm. BUT, I still expect to be hit.... If I have a problem at work or a dispute with someone, I fully expect them to slap me. This is odd, because I am now 41 & have never been slapped as an adult- think I would have been 12/13 when last smacked? This is what makes me wonder about smacking now.
Having said that, if they ban smacking, the sort of bad, abusive parents you all refer to will use other equally damaging methods of punishment, so it really won't help. Verbal abuse can be much worse than a smack.
