I just realized this evening that this is more than potty training; it's so much bigger than that...
Before we place the 10th sticker on the chart, I gave him a list of options as to what he wanted back and he said his (stuffed) tiger. After we put the 10th sticker on, I asked him again, and again, he said he wanted his tiger. (FYI, his tiger has been "watching" him use the potty from the top of the messy dryer.)
Well, I pulled that tiger off the dryer, and Mater was so happy that he gave him a GREAT BIG squeeze. It was so sweet. From that moment until he went to bed (except for when he used the potty again), he didn't let go of his tiger. He kept a tight hold on that tiger. My sister in-law, whom works in early childhood education, said to me that she thought it was a pretty ingenious idea to take away and give back to them the stuff they already have, rather than buy them something new.
I guess you could say that it all goes back to the three R's. In this house, toys, blankies, and books are a privilege, not a right. He probably appreciates his stuffed tiger more now than he ever has before.
