I can hardly believe how quickly Luke is learning new things. I feel like he is on fast forward. Not only will he attempt (and usually succeed) to pull up on anything higher than 4 inches off the ground, but on Friday, he started cruising! Granted, he is very slow moving right now, but he is doing it nonetheless. I saw him pull up on the couch in one location, and when I looked back, he'd moved himself down to the end - of course, reaching for something I'd put up there, thinking it was out of his reach. My babyproofing is seriously being tested already!
