He's still in his infant seat, as long as we can fit him in it. Just easier to put him in the car without have to struggle with a wiggling baby. We do that in the house, then take him out to the car. Plus, the carrier is really convenient when we're out shopping, and if we go out to eat (the straps keep him in, since he has a tendency to want to squirm out of seats).
Also, I caught him pulling himself up today. He also has a bruise on his head from falling over from doing so (I heard the thunk and the wail...had fallen over onto the wall). He's pretty proud of himself...gets up there and smiles big and laughs. I had the laptop on the floor and he couldn't resist crawling to it, grabbed the screen and used it to pull himself up onto his feet. He thought it was great. I was shocked he had pulled himself up to his feet already; I only thought he had managed to pull up to his knees.
He motors it well with the crawl now, too.
He'll be 8 months in a week, too. His first year is coming up pretty quick.
