My son is 15 months old and is almost completely potty trained, we are still working on number two, but as far as pee pee we haven't had an accident in two weeks. What I did: bought a potty seat that fits onto the big toilet they have them for ten bucks at walmart and they have a guard on them that keeps the pee in the toilet, I would superglue it into place though, I then took my son to the store and let him pick out his own "big boy pants", I then found a reward that he liked, that he gets only whenhe goes potty, you can use candy, cookies, stickers, I ended up useing cheese. Every time I took him to the potty and he went he gets a small piece of cheese, and every time he stays dry between bathroom visits he gets another piece of cheese. I just stayed consistant with him and it worked.
