Andrew pee'd on the potty tonight! He has tried before but was never successful. Lately, he has stepped out of the tub and pee'd all over the bathroom rug. Tonight, he got out of the tub and yelled, "I need a diaper!" I asked him if he wanted to try sitting on the potty and he did. As soon as he sat down, he pee'd. He immediately said, "I get a sticker!".
