Yeah, so much mobility, as I said last week. Tuck has really gotten the hang of crawling, though it isn’t a pretty, smooth action yet. But he is a madman, moving all over the place so fast we can’t even figure out how he’s doing it. We lowered the crib mattress last week because he suddenly figured out how to sit up/try to climb over the edge. This morning he’d pulled a blanket rack over to himself and gotten a blanket into his crib (that’s been moved).
