Mr W (24 mos) still has his pacifier for sleeping.

This morning he was asking for it while flipping through his books.

"I want my B! Where is my B?" he said.

"W-, do you REALLY want your B?" I asked?

"Yep!" he said.

"I'll show you your B!" I replied.

I grabbed a book of his that had a letter on one page with objects on the other. I flipped backwards from F, saying
"That is not your B!" each time.

When we got to the B page, I said, "There is your B!"

He just cracked up and said, "DAD!!!"
