Will peed in his potty for the first time on Sunday. But I missed it (I was playing video games with my friend Dan). So last night I got Will ready for bath, he sat on the potty for awhile, did the tuck, and ordered me to leave (he insists on privacy when he's in the bathroom, even though he does not give it when the roles are reversed). I peeked in on him several times to encourage him, and each time he ordered me out of the room. But after several tries, running out of and back to the bathroom a few times and then resetting and re-tucking, he couldn't do it. Eventually I had to give him his bath, so even though he wanted to keep trying, I had to take him off of his seat on the potty, and he was not happy about that.
After his bath, I had him wrapped in his bath towel and he again insisted on sitting on the toilet. After an argument in which I told him he either had to take his towel off and sit on the toilet buck-naked or go and get ready for bed, he took it off, sat and tucked, and ordered me out of the bathroom.
I went into our room to tell Erin about this situation, and the next thing I know, I hear excited footsteps, and Will runs out of the bathroom with a huge grin on his face, and literally does a Tiger Woods fist pump and yells "YEAH!" Sure enough, I checked and there was pee in the potty. We were very excited. Will got a gummy dinosaur (he gets a treat after every successful use of the potty - a trick we learned from Cate's parents), and he just beamed for the remainder of getting him ready for bed. So we'll see if he can do it again tonight!
