After dinner we require our children to say "Thank you" to the preparer of the meal and to say "May I be excused."

This evening The Otter was finished with his meal so we said "Tell me mommy 'Thank you'."

He said, "Dank you".

Then we told him "Say 'May I be excused Please.'"  (Yes, of course we know he is only 9 months and can't grasp 5 word sentances.)

He said "ehhht, me-me" (Translated, "{burp}, excuse me."  He can't burp so he makes the vocal sound, ehhht)
