About two o'clock
All this while Daddy Brown and Mother Brown knew nothing about their children having gone out in the night . But Mother Brown soon found it out . I 'll tell you about it . About two o'clock every morning -LRB- when it was still quite dark , and when it was yet night , though you could call it morning -RRB- , Mrs. Brown used to get up , and slip into the rooms of the children to see if they were covered up . For little folk often kick off the bed clothes in the night , and so get cold . Mother Brown did not want this to happen to Bunny and Sue . This time , though , when Mother Brown went softly into Sue 's room , to see if her little girl was all right , she did not find Sue in her bed .
