Nov 09, 2011 Smiling My son has a tendency to smile in his sleep. The wife and I are always wondering what is he smiling about? What is he thinking about? Does he know some inside joke, and is happy that we are left out in the cold? Is he a mastermind, and is thrilled to have us run around meeting his every demand? Is he simply just happy to be warm and clean? So he smiles, and he tends to smile for a while. Even though we wonder what he is dreaming about, we cannot help but smile too. We are a smiling family.
