Well, Sam is in a bit of a slump, weight-wise. She's weighed 13.8-13.9 lbs for the past month! Part of the problem is that I've been out of town and very busy with my thesis (hence, the lack of posts to the diary), but I think this may be a slow point in the process for her, regardless of my schedule.
Either way, she and Nora are doing very well! Keep checking back--I'll update as often as possible :)
