If there’s one thing I love about watching Sierra grow, it’s the newfound expressions she discovers every few weeks or so.

Over the past two months, Sierra has become more and more expressive – first, smiling; then, laughing, moving and a wild waving that has become the custom expression for “OMG THIS IS SO COOL!”

It’s hilarious, and totally fun. Sierra finds joy in everything, and she lets us all know. She’s begun growling, screeching, giggling and hopping, all in the past month.

This picture, from daycare, shows just how fun life can be for a little nearly-six-month girl.
