Difference between "asleep" and "sleeping"?
I know *asleep* and *sleeping* are interchangeable in many cases. But in these situations, I am not sure. I read stories to my son after he went to bed. After reading the stories, I stayed for some time and tucked the quilt for him. When I came out of his room and met my wife, she asked "**Is he asleep**?" or "**Has he fallen asleep**?", or "**Is he sleeping**?" In the morning, I woke my son up before he went to school. But later I found he did not get up. His eyes were closed. I asked, "**Are you still asleep**?" or "**Are you still sleeping?**" Which is better in each situation?
