potty training

I am not patient enough for this. Teancum wants to go potty in the toilet only when it is convenient for him. So today I tried a different tactic. I put him in "big boy" underwear (which he loved) and kept him confined to the kitchen where his new potty chair was. he did really well at first and then he got to playing and would forget to use the chair. one time he was playing and then got a funny look on his face and he ran to the potty pulling his underwear down as we went. Sad to say he didn't Quite make it but he at least tried and I was very proud of him for that. I am sure there are a few of you who don't care about this but that is whats going on at our house right now trying to get Teancum to use the potty every time not just whenever the mood strikes him. if anyone has any suggestions to help me that would be awesome we have tried sticker charts and giving him a reward but he just dosen't care enough to go every time.
