No matter. We let her do what made her happy, which wasn't toddling about with a winning smile on this day. Instead of focusing on her face, I tried to capture her little hands at work.
Chubby little hands exploring, playing, and snacking--I appreciate them much more now that we no longer have any in our house. It's good to have a friend who will bring her toddler over to play with me (and my camera).
