"geen", "two, and, "b"

Those are three very popular words for Sean, lately. If you ask him what color anything is he says, "geen" (green). If he sees a letter anywhere, from the fridge, on your shirt, in a book, he'll say, "b", because he thinks all letters are "b". Anytime he counts he'll say, "two-two-two-tree-two", sometimes, he'll throw in a "one-two-tree".
We have been working really hard at teaching him to clean up after himself and we sing a song, "clean up, clean up, everybody do your share". Well, out of the blue he started singing it himself. He says "keen oh, keen oh.......body" ha ha ha. At least he has the right idea!
On Thursday, one of our few days back at work Dan started to walk out the door to start the cars and Sean exclaims, "WAIT, Daddy, WAIT!" Friday night while reading stories, he pointed to a rhino and said, "rhino", later in the story he pointed out a beaver and said, "beeber". We were both shocked. He surprises us like that everyday!
