S.D.
I think you are doing a great job. He is ready - go for it. The signs don't really lie, in my opinion. My son really didn't care if he made a mess and got wet, so I had to intrigue him. He stands up and goes pee pee - he liked to see that he controled that himself and has done great ever since. Plus, you don't have to teach him two different steps to urinating. The poo poo phase was the hardest - he saw a young boy (a year older them him) go on the potty while at a friends and has done it in the potty ever since. Hang in there. When you think it is not working, that means the next learning aha is coming! :) Also, we did not make a party out of everything. We showed great joy in the pottying (we have twins) in the toilet and "big boy", "big girl" praises. Basically, if you teach them a party should follow after pooping in the toilet, he is going to be dissapointed after a while. :)
