Jack and Tara, our   36   , were in their small beds surrounded by toy animals. My husband, Pat, and I went to sleep   37  .           38   after midnight, Jack quietly touched me. “Mommy, I want to stay with you. I promise I won’t take much room.” I shifted   39   to make room. My son soon fell asleep.        An hour later, Tara cried and I carefully went downstairs. “Mommy, my   40   is all stuffed up（堵住）. I can’t really breathe very well. Will you please   41   with me a little while?” Tara doesn’t often get up at night,   42   I decided to be there for her. She soon fell asleep. I returned to my own bed. I was determined to sleep. But to my   43   , I found Jack sleeping on my side of the bed. He looked so   44   that I couldn’t remove him. Quietly and carefully, I lay down between  45   and Jack.        I did manage to get some sleep   46   I heard Tara’s voice again. I returned to   47  Tara. “Mom, please lie down with me a little bit, I had a bad dream, and I’m so   48  .” “Of course, honey. It was only a dream. Mommy’s here and   49   is okay.” We fell asleep   50   each other’s arms.        Even in my sleepy state, I thought of   51   these nights of merry-go-round（一连串的繁忙活动）beds will be over. In their place, my twins will be grown.   52   before I’m ready, our children’ rooms will be much too   53   and empty. So it is especially on days when I’m worn out after a night on this mom’s merry-go-round that I remind   54   that these very days and nights are, in fact. “the good old days”, ever so   55  .
