There are more and better resources now than ever to learn about raising a children. I was spanked and I’d imagine most people before me for spanked. Before that you cut a switch and we’re essentially lashed. Those practices are now considered wrong with one being literal legal child abuse. Things like positive reinforcement, physical contact, and just love are shown to raise much better people. As far as nursing, diapers, and all that jazz, there’s endless options to read about and experts to consult with. I’m sure you remember some of your childhood and some of the events that you now know were good and bad. Use that knowledge as well. Nobody was born with all of the knowledge, use the support around to gain it.
