Sheldon and Gregory

With Maura being so tired all the time, the rest of the family pitches in to keep Gregory happy. Sheldon used to play with this same dollhouse when Grace was a child.

"And this is where the Mommy is sleeping." Gregory tells Sheldon. "Mommy says I will be a good big brother. Do you think so too, Uncle Sheldon?"

Sheldon tells him, "Oh yeah. You'll be the best big brother of all. I just know it."
