Jack is 17 months old now, and starting to talk, sort of. The kitty is "kee" and a ball is "baw." If he wants something that he can't reach, he points and says "dis."
As Jack's grandparents, my wife and I have patiently awaited his beginning experiments in oral communication with high anticipation. We don't have names yet. We'd prefer reasonable derivatives of Grandpa and Grandma.
I'd rather not be Pee-Paw or Poo-Paw, if at all possible.
During our last visit, it occurred to me that Jack might not know who these big people are who periodically show up at his house for a week or so. One Saturday afternoon, we were all gathered in the living room. I put Jack on my knee.
"Jack," I said. "Do you know who I am?"
"I'm your mommy's daddy."
More thoughtful staring.
"Jack has a mommy and daddy, and Jack's mommy has a mommy and daddy. Where's Mommy?"
Jack points to Mommy. Bright lad.
Jack points to his dad. This kid is an Einstein.
"So ... see? I am Mommy's daddy."
A few hours later I returned from a trip to the grocery and walked into the kitchen. Jack was there, with Mommy. He looked up at me, smiled, pointed, and said "Mommy-daddy!"
