Back on topic, I have a 1 yr old. I love him very much, more than I could ever envision loving well..anything. But I wouldn't rule out spanking him in the future. I wouldn't rule out not spanking him.
I was spanked as a child, so was my wife. She actually got the belt. I remember my spankings, I remember the ones that worked, and the ones where I realized a tanned hide was a small price to pay to hunt frogs for another hour after dark. I hope I'm a good father and don't screw it up, either by being too punitive or too lenient. It is a really hard path to tread, until you do.
