Our son, Alex, has begun to walk. He's still at the stage where he only takes two or three steps before losing his balance, but you have to start somewhere. He also is managing to stand unaided for however long he manages to not notice he's doing it. So far the longest duration seems to be about 15 seconds. He also likes to push around his cousin Jack's walker and is just pleased as punch with it until he hits the wall - he doesn't know how to steer yet.
Here's a quick rundown of his vocabulary:
Kat (whispered for some reason) = cat
Guh or Daaa = dog
dat = that (?)
ba ba ba = bye (he's learned to wave, sometimes at himself)
muh muh muh... = I'm upset (unfortunately, it doesn't yet mean "mom")
da = dad (maybe)
