A tender moment

Sheldon watches the two most important people in his life. He is part of a family again.

He wants to laugh as he watches Grace grab tight to Fiona's hair, yet fights back tears because of the depth of emotion he's feeling.

He doesn't know what kind of parent he'll be, the thought of changing diapers terrifies him, but he'll try to overcome his fears. He wants only good things for his wife and their child.
