In this age of Internet chat, videogames and reality television, there is no shortage of mindless activities to keep a child occupied. Yet despite the competition, my 8-year-old daughter Rebecca wants to spend her leisure time writing short stories. She wants to enter one of her stories into a writing contest, a competition which she won last year.

As a writer, I know about winning contests – and about losing them. I know what it is like to work hard on a story only to receive a rejection letter from the publisher. I also know the pressure of trying to live up to a reputation created by previous victories. What if she doesn’t win the contest again? That’s the strange thing about being a parent. So many of our own past scars and destroyed hopes can resurface in our children.

A revelation (启示) came last week when I asked her, “Don’t you want to win again?” “No,” she replied, “I just want to tell the story of an angel going to first grade.”

I had just spent weeks correcting her stories as she spontaneously (自发地) told them. Telling myself that I was merely an experienced writer guiding the young writer across the hall, I offered suggestions for characters, conflicts and endings for her tales. The story about a fearful angel starting first grade was quickly “guided” by me into the tale of a little girl with a wild imagination taking her first music lesson. I had turned her contest into my contest without even realizing it.

Staying back and giving kids space to grow is not as easy as it looks. Because I know very little about farm animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting my daughter’s experience.

While stepping back was difficult for me, it was certainly a good first step that I will quickly follow with more steps, putting myself far enough away to give her room but close enough to help if asked. All the while I will be reminding myself that children need room to experiment, grow and find their own voices.
