Ollie picks up more and more words every day.
Cat. door, no!, book, clock (which was his first real word, btw), come, and go (and so much more i'm forgetting). He uses come as a catchall demand for something... For instance he'll hand me two pieces of train track and say, 'come' when he wants me to put it together, and he'll give it to me and say, 'go' when he's all done. It's cute.
He is scary good at picking up words. Scary because I have to watch what I say even more now, because he will repeat a random word from something I've said. And then it'll be part of his lexicon.
He's doing well. He had a checkup a few weeks ago and I forgot to update his weight/size stats. He's healthy and walking around and eager to explore everything (especially if we go someplace new).
