What are you doing?

Yesterday Annika came up to me and clearly said "What are you doing Mommy?" At first I thought it was my imagination, but then today Austin was in the kitchen and she walked right up to him, looked up at his face, and said in a clear voice "Austin, what are you doing?" So it wasn't my imagination. It was the cutest thing! Austin was so excited Annika spoke a full sentence to him. Before we know it she's going to be talking our ears off.
