Cuffy Bear in "Cuffy Bear Grows Sleepy"

She had noticed for several days that Cuffy and Silkie were growing sleepy. And to tell the truth, Mrs. Bear was becoming sleepy herself. That very night she and Mr. Bear went to bed a whole hour earlier than usual. And the next day they never minded at all how cold it grew outside or how much the wind howled. For not one of Mr. Bear's family waked up at all! They just slept and slept and slept, the whole winter long.
