A.W.
When my son was potty training I kept a sticker book on the back of the toilet and every time he went he got a sticker. He got 2 for going number 2 since that's a little more involved. After he got 10 stickers he was able to pick something to do - go to the park, watch a movie, go out to pizza or pick a small toy from a box (dollar store type stuff). This system really worked because it involved consistent positive reinforcement.
I was your age when I had my son - he is 10 now and I am doing it on my own. I know how difficult it can be to raise a child when you yourself are so young. It can be a real challenge - keep your head up tap whatever resources you have - support groups, grandparents and other parents in your neighborhood.
Good luck with the potty training!
