WEll, it's been quite a while for me, being as I have one on a mission right now, and another one soon to go, but my oldest was potty trained by 17months old, and the second was about 21 months, and the last, well, he trained himself, just by watching his older brothers. None of my boys were hard to train, so I don't know if that's true about boys being harder than girls (since I have no girls!) But one thing I am big on, is praise when they do something good, like going on the toilet. I used to sit them on the toilet and tell them how good they were, even if they didn't do anything, and we really celebrated when they did. And when they missed and went not in the toilet, I never scolded- we just cleaned it up without saying a whole lot. We had a party hat and the blower things and stuff, so when they did pee in the toilet, we literally had a party!! Also, sitting them on the toilet I hear when you are running the bath water I hear works, not sure if it did, but I know I tired that too! Well, don't know if my blabbling helped, but I wish you the best of luck with it. It doesn't hurt to try!
