I love watching Brennan's growth too. His responses get cuter and more clever all the time. I can't think of all the examples, but, for example, I laughed today when, after I told him that he's an awesome kid (he put his breakfast dishes on the counter before I asked him to), he agreed, "Yeah, I-yam a awesome kid!"
I should get a picture of Brennan with his friend Wyatt who lives across the street - it's a relatively narrow street in our complex and they live literally right across. If Wyatt's sitting in his window upstairs at his house and Brennan goes outside, Wyatt calls "Hi Brennan! Wanna come play at my house?" or "Come play in my bedroom with me!" or whatever. Brennan, likewise, will call similar invitations from our house when Wyatt's outside. Because Wyatt is almost always outside, when we get home from an outing Brennan runs over and they meet each other in a 'best-0f-friends' embrace. It may be a long time before I get a house with a garage or fenced yard, but in the mean time at least Brennan has his kindred spirit.
