Thomas cut his very first tooth!
He stood up without holding onto anything for the first time! (Not standing up from the floor, but letting go of the table or couch and balancing by himself.) He was so pleased with himself that he stood there and squawked until I looked at him and applauded, and then he fell over. :)
I really think he'll walk before the end of his first year - yesterday evening he cruised everywhere and when he got to the end of the couch or table he'd take a last step, balance, lean in the direction he wanted to go, and then fall to his knees. I don't think it will take too much longer for him to realize that he doesn't have to fall over!
