Potty Training

Our little boy is 2 1/2 and had been showing a little bit of interest in potty training so I bought him some little boy underwear (they are so cute and little by the way). Last week my sister-in-law (who babysits for us) and I worked hard at getting him to use the toilet but he just wasn't getting it. In fact one night he went right next to the toilet. So we kind of gave up and went to pull ups. The day before yesterday he wanted to get on the bus with my older son and my brother-in-law told him that only boys who use the toilet can ride the bus. He was devistated and cried for a long time or so I was told. Then last night he says he wants to use the potty, but he has said this before because I think he feels big just sitting on it. So he crawled up on it and low and behold he went #1. I'm not sure if it is what my brother-in-law told him or not but I was so proud. Who would know that something so little would make me so happy?
