My 4yo at breakfast told us he finally knew how Daddy became a Daddy. We waited very anxiously to see how on earth he'd anything about the birds and the bees.

DS then reports, "Daddy, while you were asleep, Mommy bought you glasses. Then when you woke up, you put them on and you were a Daddy!"

Whew, our very innocent four-year-old is still blissfully innocent.
