Good Night-Night

I used to always ask Keegan if he had a good rest when he woke in the morning or after his nap.  He would shake his head "yes" and say, "uh, huh".  Now, before I can say anything, he says, "I had good night-night".   He will sometimes even ask one of his little stuffed buddies, "good night, Elmo?", as he takes him into his arms for a big hug.  Elmo is one of his favorites; sometimes Keegan will even let Elmo brush his teeth!
