I mostly agree with the response posted by Linda B. I actually disagree that he's being deceitful. Kids at this age are smart but actually their minds work from an area at the back of the brain that is responsible for feelings not structured, reasoning skills like the front of the brain uses as they grow older. I would definately just be consistent in whatever you choose and stay on the positive tip otherwise it will become a battle of wills. It was more challenging to potty train my son than it has been my girls. We had luck using a potty chart on the back of the bathroom door and we let them put stickers on every time they went pee in the potty. We also read books and watched "Once Upon a Potty" to encourage this acquired skill. For boys, start out by having them sit because otherwise you'll have pee all over the place but as they grow bigger/taller then we even had my son aim for a cheerio or piece of toilet paper that we'd throw in the stool before he went. We also taught him to put the seat down for common courtesy. And, always finish up by washing our hands. Good luck!
