I too was raised in a way where I got a smack on the bottom (usually hand, sometimes wooden spoon) as a young child when I did something wrong. I don't remember it happening as much with my brother or sister though (not sure if my parents changed their parenting style or I don't remember it cause it wasn't happening to me). I don't feel like it negatively effected me emotionally in the long term or anything, however, I've found myself having to stop myself a few times from smacking DD as it seems to be an almost in-built knee-jerk reaction to me. I understand that people have the right to parent their kids how they like, but it's not what I want for my family.
