My son is almost 2 1/2 & was potty trained in one month & I have the luxury of staying at home alot. Here's what worked for us: At first I let him run around naked, every time he used the potty, I bribed him with his favorite treat & we made a BIG deal of the deed! We clapped & hooted & hollered EVERY time he went & gave lots of praise. He also enjoyed empting his own DEED into the toilet himself out of the little potty. Step 2, I put real underwear on him, no pants, no shoes. Once he peed & pooped in those a couple of times, he caught on real fast that he did not like it! We stayed on this step for a good while. Step 3: Once they get #2 down we started putting on pull-ups for travel ONLY. I found that he would pee or poop in his diaper EVERY time we left the house b/c he was used to it & it was convenient for him. Once I started putting on pull ups with his favorite character on it, he started asking to go to the bathroom even in public. I simply told him when I was putting them on, "We don't want to pee on Diego" & showed him all the pictures on the pull ups. I also had to prompt him before every trip, "We don't want to pee in our car seat" & "Don't forget you don't have on a diaper, you have to use the potty when you need to go". This worked like a charm for us. GOOD LUCK! BTW- They are all different & learn at different rates. One thing I found with mine was, it did not happen until HE was ready.
