"Oh no! I've lost Devon!" he exclaimed, "Where could she be?"
He got on his hands and knees, crawling along the foot of the sofa.
"Nope, not under there."
He smiled as he passed the little toes sticking out from under the

"Well
, she's not here," he said, ignoring a giggle. "I guess I'll have to eat
this macaroni and cheese all by myself."
