This maybe for older members, but everyone that has input can pitch in. While most of us can't remember our own potty training we do sometimes have memories of others training. I'm a early Baby Boomer and lived in Chicago so there were lots of kids. We were often in other kid's homes. I saw a lot of kids being trained. Age was one thing, they started very early by our standards. And often very rigid methods. It seemed that most mommies had particular ( and frequent times for the child to be put on the potty). I'll let this start and a little later I'll add some of the details of potty training in the 1950s.
