Potty progress

I recently realized that Luke needs to sit on the potty more than once a day before bathtime. So, about a week or so ago I started asking him to sit on the potty 3 or 4 times a day, and he readily agreed each time (which is in and of itself progress, because until about 2 months ago he didn't want to sit on the potty at all.) He started pee-peeing almost every time he sat down, and just now, for the first time, he told me he needed to sit on the potty again. He got his pants and diaper down all by himself, and he sat on the potty and went! I was so pleased, and so was he. I realize this is a very small step on the road to being potty-trained, but I really feel like we're starting to make some progress.
