I can't speak from parenting experience, I haven't been there yet. I definitely do NOT condone any smacking for very young children (under 3 or 4?). However have not ruled it out for reasons explained by doubletrouble, crazycatlady and starfish. I do not judge people who smack their kids. We are all learning, there is no big book. I do think there is a massive difference between a smack on the hand when the kid is about to put a stick in a toaster, and beating a child or using instruments.

From a child's perspective who was smacked (rarely, mind you), I was not scared of my parents. I didn't quiver with fear or anything, I just knew I'd messed up and was in biiig trouble!! The moments of discipline that have stuck with me are the words, knowing I had really disappointed and upset my parents. I felt so guilty and still do as an adult. I feel like my parents did a good job really, and I think I'll parent my children in the same style.
