I went to Target today just browsing through the aisles and then came across one of those little seat thingies you put on top of the toilet so your kid doesn't fall in - so I bought one. And after our dinner at our favorite sushi restaurant tonight, we opened it up, stuck in on top of the toilet and explained to Christian what it was. We asked him if he'd like to try it. He replied with a big nod, "shyesh" (his way of saying "yes") and so we took off his diaper and put him on top of the seat. He looooved it. He sat in there for about 5 minutes and did not want to come down. We even gave him a book to read. And then afterwards, we gave him some toilet paper and he patted his "ba-dunk-a-dunk" as we call it. Of course he didn't really pee or poop (although we were really wishing he would).
But look at that face - it encompasses a look of satisfaction, accomplishment and excitement. Priceless.
