Update:
We went for her well check yesterday. Dr. B was very encouraging about her growth...almost 3 pounds in one month! She is on track with her development and got some shots. It was a long morning and Vivian was so patient, thank goodness. Here are the stats:
weight: 11 lbs, 7 oz (75th%)
length: 23 inches (75%)

-Kate likes to cuddle! What I really mean is that she likes to be held. It could be that I've conditioned her to prefer that, though, because I love cuddling with her :) It does become an issue when I've got lots of housework to do or Vivian wants to play.
-Her smile is very sweet. We can count on a smile whenever she looks at her mobile or the star that lights up.
-She goes to bed around 8 and wakes up around 7. She usually eats twice in that time, though.
-Her waketime activities include watching Vivian eat at the table, playing on the floor, or staring at mom. She also plays by herself in her crib once a day (watching the mobile).
-She is pretty tolerant of Vivian. Sometimes Vivian crawls all over me while Kate is nursing and it doesn't seem to phase her unless she's getting elbowed or poked in the eye.
-She eats every three hours (give or take a little) and naps (not in her crib) for about 1.5 hours in between feedings. She's awake a lot more in the evenings, though.
Kate is 2 months old today! I am holding her right now as she's falling asleep, so I can't type much. Later I will add to this post about how she's doing, but I wanted to share these cute pictures asap so you can see how much she's growing!

Happy 2 months, Kate!
