The amount of sleep was based on their reporting of a child's usual bedtime and wake time.

VOA: special.2010.06.09

That is heaven's part, our part To murmur name upon name, As a mother names her child When sleep at last has come On limbs that had run wild.

这是天国的本分，我们的本分,喃喃念着一个个名字，像一个母亲叫着她的孩子们,当睡意最终降临,那跑野了的四肢。
