Growing, growing, and growing.  Amazing how quickly they grow and develop.  Looking at the birth weights, and then their current weights, the pups have grown about 400%.  They've started to walk, pushing themselves up on all fours.  They manage about two steps then, opps, the sideways roll.  It is still pretty much eat, then sleep, then eat again.  They changed their sleeping arrangement a bit.  Before, they laid side by side, kind'a like a row of sausages.  Now, they are most likely in a pile, taking turns being the on top of the pile.  They don't remain still very long, even when sleeping, one or the other is stretching, yawning, or just twitching.
