So this evening I said, "Let's go upstairs and get our jammies on." And Andrew got down off the couch (and daddy's lap - his favorite spot!) and walked up the stairs with me. No cries of protest, no demand that he be carried. After changing, he walked back downstairs to brush his teeth, picked out his own storybooks, and walked back to the office to give daddy a hug and kiss goodnight.
I am absolutely floored. And pleased. And in love with this big kid.
