Yesterday Griffin hit the 6 month mark. He's 29.25 inches - so only slightly longer than Penny at this age. Weight wise he's smaller, but I'm not sure exactly how much. I'd guesstimate his weight at 19 lbs.
We're still nursing, but things have slowed down. He nurses for comfort and then overnight.
He's sitting up well, reaching for everything, and rolling. My guess is he'll start crawling by 8 months (or sooner) but it will certainly be before his sister did. He's just a much more active and physical baby.
He's also a horrible sleeper. Waking up from his nap now, so this is all the time I have!
