Task: Question Answering
Input (English): It is late at night and the sun has gone down, and my kid is sleepy. It is bed time. He is still very little though and needs some help going to bed. I take him to his room and make sure he gets ready before going to sleep. He brushes his teeth and washes his face so he stays clean and healthy every day. Once he is done, he changes into clothes for sleeping so that his other clothes stay clean while he sleeps. He crawls into bed and I pull the covers over him. His head rests on his pillow so he is comfortable and can fall asleep better. He is afraid of the dark like me, so I leave a nightlight on for him in the hallway. A little light at night can help you feel better and more relaxed, but too much light keeps you awake. I tuck him in and say goodnight and let him fall asleep. 
Question: Why did the child need to go to bed?
Output (English): it was bed time
