Going into James' room to transfer the laundry from the washer to the dryer, I heard James humming tunefully with a Scrabble tray in his mouth, moving his fingers as if the tray were a recorder. I got a turn and played "Twinkle, Twinkle Little Star" and then gave it back to James, and requested "Old MacDonald Had a Farm". By this time Isabel had come in, and James hummed and vocalized to the song, and at the end you could hear the "E-I-E-I-O"! Isabel played "Baa, Baa, Black Sheep" and we took turns after that. A couple of the cutest were "Gonna take a walk outside today", that Isabel played (from Milo and Otis), and James' "I Am a Pizza". He sang all the verses, you could tell, and at the end he very sadly and dramatically hummed the last part--"I was a pizza, now I'm a MESS!"
Isabel has identified with Otis. Now instead of quoting the lines word for word, she replaces "Otis" with "Isabel". I've also found out what the kids think I mean when I say "Take a bow!" Can you figure it out? Isabel ran from the room, shrieking "Yay!" and James stood still, emphatically nodding and saying "YES". Luckily for me, he signed what he thought I'd said, and then I knew where Isabel had run to.
