Dear K.,
My son was easier to train than my daughter so don't believe all the stuff about boys being more difficult.
Both my kids were easy. They hated a wet or dirty diaper. I took them in the bathroom with me when I went and started putting them on the toilet so they could have their turn pretty early on. They would have nothing to do with the little potty chairs.
Well, that's not true...they dragged them around the house and stashed toys in them, but never would go except on the big potty. My dad built a wooden potty stool for my daughter so she could get on the toilet by herself and my son used it with delight 10 years later. We still have it. I personally think kids are able to grasp the whole concept early on.
"This is what the toilet is for."
My son and dad had a thing about peeing outside on a rock when we went to visit.
Grandpa peed outside on the same rock with my nephew too.
I hope that doesn't sound gross, but it worked and my son was super easy to potty train.
Best of luck!
