Isaac is crawling, about 6 steps at a time, pulling himself up on things and starting to walk along them a little, and he has figured out how to go up AND down stairs. Only a couple, but still. He has no fear. It all happens so fast! The other day he was in the living room, heard the tub running, so he went up the stairs, down the hall, turned into the bathroom and went straight to the tub. It's a good thing he can't get in it himself.
