Family myth:
My FIL did not speak until he was almost four.

First thing he said was:
"Mother, may I please have more milk in my cereal; it is tending to be a bit dry."

His mother:
"You spoke! Why have you waited so long?"

Him:
"Until this moment, everything had been just perfect."

There seem to be some kids who want to completely master a system (speech or otherwise) before they use it. I wonder if you 'll see more of these nothing....nothing....nothing...everything! moments as he grows up.
