My toddler gravitates to the aunt with the big belly.  Interested.  “There’s a baby on there.”

He got it. “Where’s the baby?” He points to the pregnant belly.

Later,  he goes up to the aunt, wanting something. She asks, “Show me?” He takes her by the hand,  leads her to the couch,  climbs up beside her and just sits there, cuddling.

He wants to sit by that belly.  He shares snacks with his aunt,  who he hardly knows. He knows there is something special coming.
